IR illuminator flood lights or infrared lights can be used day or night and with black and white cameras to illuminate an area.

IR or infrared satellite imagery is sort of a temperature map. The weather satellite detects heat energy in the infrared spectrum (infrared energy is invisible to the human eye). The satellite image displays objects(whether clouds, water or land surfaces) based on the temperature of the object.

Infrared technologies provide tremendous value to our modern-day society. The need for easy-to-fabricate, solution-processable, tunable infrared active optoelectronic materials has driven the development of infrared colloidal quantum dots, whose band gaps can readily be tuned by dimensional constraints due to the quantum confinement effect. In this Perspective, we summarize recent progress in the development of infrared quantum dots both as infrared light emitters (e.g., in light-emitting diodes, biological imaging, etc.) as well as infrared absorbers (e.g., in photovoltaics, solar fuels, photon up-conversion, etc.), focusing on how fundamental breakthroughs in synthesis, surface chemistry, and characterization techniques are facilitating the implementation of these nanostructures into exploratory device architectures as well as in emerging applications. We discuss the ongoing challenges and opportunities associated with infrared colloidal quantum dots.

Plasmonic devices confine light to nanometer-sized regions of space, which turns them into effective cavities for quantum emitters. QDs possess large oscillator strengths and high photostability, making them useful for studies down to the single-particle level.

One of the fastest moving and most exciting interfaces of nanotechnology is the use of quantum dots (QDs) in biology. The unique optical properties of QDs make them appealing as in vivo and in vitro fluorophores in a variety of biological investigations, in which traditional fluorescent labels based on organic molecules fall short of providing long-term stability and simultaneous detection of multiple signals. The ability to make QDs water soluble and target them to specific biomolecules has led to promising applications in cellular labelling, deep-tissue imaging, assay labelling and as efficient fluorescence resonance energy transfer donors.

Despite recent progress, much work still needs to be done to achieve reproducible and robust surface functionalization and develop flexible bioconjugation techniques. In this review, we look at current methods for preparing QD bioconjugates as well as presenting an overview of applications. The potential of QDs in biology has just begun to be realized and new avenues will arise as our ability to manipulate these materials improves.

We report here a nanostructure that traps single quantum dots for studying strong cavity-emitter coupling. The nanostructure is designed with two elliptical holes in a thin silver patch and a slot that connects the holes. This structure has two functionalities: (1) tweezers for optical trapping; (2) a plasmonic resonant cavity for quantum electrodynamics. The electromagnetic response of the cavity is calculated by finite-difference time-domain (FDTD) simulations, and the optical force is characterized based on the Maxwell’s stress tensor method. To be tweezers, this structure tends to trap quantum dots at the edges of its tips where light is significantly confined.

The ability to shape light has revolutionized imaging, optical trapping and both quantum and classical communication. The simultaneous control over both spatio-temporal intensity and polarization structures requires new approaches to optical devices such as meta-materials and -surfaces while at the same time the handedness of structured light lends itself to imaging, probing and manipulating the geometry and potentially chirality of matter. In addition, the generation, propagation and interaction of structured light with matter is governed by topological invariants and conservation laws, which add a complex mathematical component to this exciting and interdisciplinary field.

The word interdisciplinary can be broken into its parts: inter-, which means "between" in Latin, and disciplinary, which is from the Latin disciplina and means teaching or knowledge. Interdisciplinary means between fields, but they don't have to be unrelated disciplines.

Silicon spin qubits have achieved high-fidelity one- and two-qubit gates1,2,3,4,5, above error-correction thresholds6, promising an industrial route to fault-tolerant quantum computation. A significant next step for the development of scalable multi-qubit processors is the operation of foundry-fabricated, extendable two-dimensional (2D) quantum-dot arrays. In gallium arsenide, 2D arrays recently allowed coherent spin operations and quantum simulations7,8. In silicon, 2D arrays have been limited to transport measurements in the many-electron regime9.

Here, we operate a foundry-fabricated 2 × 2 array of silicon quantum dots in the few-electron regime, achieving single-electron occupation in each of the four gate-defined dots, as well as reconfigurable single, double, and triple dots with tunable tunnel couplings. Pulsed-gate and gate-reflectometry techniques permit single-electron manipulation and single-shot charge readout, while the two-dimensionality allows the spatial exchange of electron pairs. The compact form factor of such arrays, whose foundry fabrication can be extended to larger 2 × N arrays, along with the recent demonstration of spin control10,11,12 and spin readout13,14, paves the way for dense qubit arrays for quantum computation and simulation15.

The ongoing miniaturization of solid state devices often leads to the question: “How small can we make resistors, transistors, etc., without changing the way they work?” The question can be asked a different way, however: “How small do we have to make devices in order to get fundamentally new properties?” By “new properties” we particularly mean those that arise from quantum mechanics or the quantization of charge in units of e; effects that are only important in small systems such as atoms. “What kind of small electronic devices do we have in mind?” Any sort of clustering of atoms that can be connected to source and drain contacts and whose properties can be regulated with a gate electrode.
