摘要：

Ce-doped yttrium aluminum garnet (YAG:Ce) is an important phosphor in the phosphor-converted white light emitting diode (WLED) while YAG:Ce-based WLED is cold and blue so that impair the performance of WLED. In order to achieve warm WLED, in this study, CuInS2/ZnS colloidal quantum dots (CIS/ZnS QDs) has been designed and synthesized. The crystal structure, photoluminescence and thermoluminescence have been measured and analyzed. The lighting film was realized by adding CIS/ZnS QDs into YAG:Ce-silicone, fabricating with InGaN-based blue LED to display warm white light which Commission International de L'Eclairage chromaticity coordinates at (0.3814, 0.3237) and correlated color temperature of 3415K. Our experiments show that film consists of YAG:Ce and red-emitting CIS/ZnS QDs is able to achieve warm WLED with desired results.
