Alloyed ZnxCd1−xSe quantum dots (QDs) covering the UV–visible spectral region are successfully synthesized using 3-mercaptopropionic acid (MPA) as a capping agent. The optical properties of the alloyed QDs are determined on the basis of different ligands, reaction times, pH, Se/Zn molar ratios, and Zn/Cd molar ratios. The band gaps of the as-prepared QDs can be tuned by adjusting the compositions of the dots, and the quantum yield of ZnxCd1−xSe QDs is 33%. All results indicate that ZnxCd1−xSe QDs can be potentially applied in photochemical devices.
