We report a chemical method to prepare Cu/In inks or Cu–In inks, from which CuInS 2 films are formed. Cu, In and Cu–In nanoparticles are initially synthesized by a polyol method, and then dispersed in solvents to form inks. Metal films are subsequently obtained by drop-casting the Cu inks and In inks in sequence or Cu–In inks directly. The sulfurization of the metal films is carried out in...
Junction field effect light emitting transistors (JFELET) were fabricated using silicon quantum dots in a conducting polymer matrix. The quantum dots with photoluminescence emission centered at 650 nm were used. I-V and light emission characteristics for typical light emitting transistors are presented.
