ABSTRACT

A study is reported of the properties of a new phosphor material based on a highly refractive leadsilicate glass and microparticles of yttrium-aluminum garnet doped with cerium ions (YAG: Ce3+). The mass percentage fraction of YAG: Ce3+ microparticles in the material was varied from 50 to 90%. The optical properties of the phosphor were examined, as well as its thermal properties when used as a primary optical material in high-power light-emitting diode (LED) units. The results obtained reveal problems of excess heat removal from an LED structure, which appear on passing from phosphor binders based on silicone elastomers to glasses, and demonstrate that the phosphor developed in the study is promising for obtaining warm white light.
