General synthesis of I–III–VI2 ternary semiconductor nanocrystals

Abstract

Metastable orthorhombic phase of AgInS2 nanocrystals with various shapes, including particles, rods, and worms, have been obtained to demonstrate a facile and effective one-pot chemical route for the synthesis of high quality I-III-VI2 ternary semiconductor nanocrystals (AgInS2, CuInS2, AgInSe2) with controllable shape and size.

Facile solution-controlled growth of CuInS2 thin films on FTO and TiO2/FTO glass substrates for photovoltaic application

“…The mechanism for the growth of CuInS 2 thin films is proposed to include process of nucleation, growth, and aggregation [17][18][19][20][21]. At the early reaction stage, some Cu 2+ ions are reduced to Cu + ions by ethanol and Cu + ions react with In 3+ and S 2− ions, which are released by C 2 H 5 NS in the solution, to form CuInS 2 nuclei under the solvothermal condition on the substrate surface.…”

Synthesis of AgInS2 semiconductor nano crystals by solvothermal method

“…It might be used in light emitting diodes, nonlinear optics and solar cells [1]. Semiconductor materials, such as AgInS2, CuInS2 and CuInGaSe2 have been broadly investigated for photovoltaic device applications [2,3]. So far, substantial attempts were made to the preparation of AgInS2 thin films and single crystals [4].…”

Synthesis and formation mechanism of CuInS2 nanocrystals with a tunable phase

“…Various morphologies such as nanowires, nanorods, nanobottles, hollow nanospheres and hierarchical microarchitectures [10][11][12][13][14] have been prepared by a sol process, solvo/hydrothermal procedure, or single-source pyrolysis. [15][16][17][18][19] Even though there are two main reasons that arouse interest in the study of a new phase of CIS: one is that the two metastable wurtzite and zinc blende CIS phases are considered as counterparts of breaking away from their natural preferences. Therefore, controllable synthesis of metastable materials can enrich the crystallography.…”
