Low temperature synthesis of highly bright green emission CuInS2/ZnS quantum dots and its application in light-emitting diodes

Colloidal Quantum Dots: Synthesis, Composition, Structure, and Emerging Optoelectronic Applications

“…In addition, the method can also synthesize doped [58] and core-shell structures. [59] Deng et al [60] successfully prepared CuInS 2 QDs from CuI, In(OAC) 3 , ODE, dodecanethiol (DDT), and sulfur powder. When the reaction solution was cooled to room temperature, it was injected with zinc stearate and heated to 240 °C for 2 h. CuInS 2 /ZnS QDs were obtained after precipitation and purification.…”

Synthesis and structure design of I–III–VI quantum dots for white light-emitting diodes

“…When Cu/Ga = 1/8, the QDs gave a pure white emission with the wide emission covering blue to red. Bing et al 39 synthesized green-emission multi-layer CuInS/ZnS (CIS/ZnS) QDs with a maximum PL QY of B85% at the peak wavelength of B530 nm via the hot injection method at a low temperature (B130 1C). They chose S-OAm (S powder dissolved in oleamine) as a sulfur source instead of 1-dodecanethiol, which supplied a high concentration of H 2 S, leading to the explosive nucleation of CIS QDs (Fig.…”

Optical properties of multinary copper chalcogenide semiconductor nanocrystals and their applications in electroluminescent devices

“…选择也是影响器件性能的重要因素 [88,89] . 若有机配体的 碳链较长, 虽然纳米晶具有较好的溶解性, 但是有机物 本身的绝缘性会影响器件中电荷的注入; 若有机配体的 碳链较短, 则纳米晶的溶解性较差, 容易发生团聚, 因此 图 9 (网络版彩色)基于Cu-In-Zn-Se-S纳米晶的电致发光器件的器件性能 [20] .…”
