Quantum dots that are based on InP has attracted a lot of attention for use in optical applications. The quantum dots have been developed in various types that are based on InP, such as InP / ZnS, InP / ZnSe, InP / GaP / ZnS. However, the initial synthesis of hot injection could not produce the required optical properties with high reproducibility.They also could not successfully support the commercialization efforts. Here, we show how to simply synthesize the InP / GaP / ZnS through the heating up process. This reaction can be completed within 0.5h and represent a full color from blue to red. If a blue light-emitting, t-DDT was used in order to prevent particle growth. By adjusting the amount of the Myristic acid showed a color from green to orange. Using a large amount of gallium chloride leads to a red color. We produced InP/GaP/ZnS QDs of high quality by this method (blue QY: ~40%, FWHM: 50 nm; green QY: ~85%, FWHM: 41 nm; red QY: ~60%, FWHM: 65 nm). We used the t-DDT not the sulfur sources reported. Compared with n-DDT, t-DDT was more reactive, which allowed for the formation of a thicker shell.
