GARNET-BASED PHOSPHOR DOPED WITH THORIUM AND LIGHT EMITTING DEVICE USING THE SAME

摘要

Provided is a garnet-based phosphor doped with thorium and a light emitting device using the same. In particular, a garnet-based phosphor having superior light characteristics and heat stability by using thorium as an activator, when compared to a conventional garnet phosphor using cerium as an activator, and a light emitting device using the same as a light source are provided.
