Tunable structural and optical properties of Ag_xCu_yInS₂ colloidal quantum dots

Abstract

Herein is discussed tunable absorption and emission properties of AgxCuyInS2 quantum dots involving wurtzite to chalcopyrite phase transformation dependent on Ag+ dopant content.

[(Ph3P)2Ag(μ-SeCH2Ph)2In(SeCH2Ph)2]: a new heterobimetallic single source precursor as a springboard to bulk, nano and thin film ternary AgInSe2 materials

“…5,6 In this regard, ternary MCs are of particular interest as they blend the extraordinary properties of MCs with the benefit of physical and chemical property tunability, along with solution processability. [7][8][9] I-III-VI 2 chalcopyrites are one particular subclass of these ternary materials (where I = Cu, Ag; III = Al, Ga, In and VI = S, Se, Te). The ternary chalcopyrites crystallize in a tetragonal body centred lattice and the structure consists of 8 atoms per unit cell rather than two atoms per unit cell as in the case of their binary analogues.…”

Mercury Chalcogenide Colloidal Quantum Dots for Infrared Photodetectors

“…Colloidal quantum dots (CQDs), as alternatives to traditional epitaxial-grown semiconductors, have emerged with unique advantages such as the ease of processing solutions, cost-effectiveness, scalability, and the ability to adjust size [49][50][51][52][53]. These advantages present a promising outlook for low-cost, large-scale, high-resolution, and small-pixel IR detectors.…”
