Synthesis of monodisperse InSb colloidal quantum dots by monomer concentration control for short-wave infrared photodetectors
Abstract InSb colloidal quantum dots combine a low bulk bandgap (0.17 eV) with a large exciton Bohr radius, enabling access to short-wave infrared wavelength within the quantum confinement regime, alongside strong covalent bonding, complementary metal-oxide semiconductor compatibility, and restriction of hazardous substances compliance.
Suppressing Colloidal Quantum Dot Multimer Fusion Leads to High‐Performance InSb Infrared Photodetectors
1 Introduction Environmentally friendly colloidal quantum dot (CQD)-based short-wave infrared (SWIR) photodetectors would open up a huge number of applications, such as LIDAR and 3D imaging for automotive and Augmented/Virtual Reality (AR/VR),[1] night vision for surveillance,[2] spectroscopy for food quality inspection,[3, 4] and bio-imaging etc.,[5] due to the low-cost, high-volume scalability, complementary metal-oxide semiconductor (CMOS) integrability and compliance with RoHS...
Shortwave Infrared Light Detection and Ranging Using Silver Telluride Quantum Dots
1 Introduction Among the various wavelengths of light, the shortwave infrared (SWIR) region holds particular importance due to its unique properties. SWIR light experiences less scattering in the atmosphere, compared to visible light,[1, 2] allowing greater penetration depth, especially in adverse weather conditions. Moreover, in the SWIR there exist spectral bands that are free of ambient background solar light, enabling ubiquitous operation of sensing and ranging during day and night.
Silver telluride colloidal quantum dot infrared photodetectors and image sensors - Nature Photonics
Abstract Photodetectors that are sensitive in the shortwave-infrared (SWIR) range (1–2 µm) are of great interest for applications such as machine vision, autonomous driving and three-dimensional, night and adverse weather imaging, among others. Currently available technologies in the SWIR range rely on costly epitaxial semiconductors that are not monolithically integrated with complementary metal–oxide–semiconductor electronics.

Halide Perovskite-Lead Chalcohalide Nanocrystal Heterostructures
Introduction Metal halide perovskites and especially CsPbX3 (X = Cl, Br, I) in the form of colloidal nanocrystals (NCs) have witnessed a rapid development in the past few years due to their ease of processing, tunable band gaps, narrow emission line width, and defect-tolerant nature, all features that make them appealing for optoelectronic devices.(1−11) Also, various groups have tackled the synthesis of NC heterostructures in which the perovskite domain is bound to a domain of another...

Solution-Phase Synthesis of CsPbI3 Nanowire Clusters via Polymer-Induced Anisotropic Growth and Self-Assembly
Solution-Phase Synthesis of CsPbI3 Nanowire Clusters via Polymer-Induced Anisotropic Growth and Self-Assembly A facile solution-phase synthesis of black γ-phase CsPbI3 nanowire clusters were developed by using poly (methyl methacrylate) (PMMA) as surfactant. PMMA was found to efficiently retard the crystal growth, thereby inducing anisotropic growth for the formation of nanowire structure, whilst the intermolecular hydrogen bonds of PMMA act a driving force for the self-assembly of nanowires.
