Abstract
A phosphor substrate converts a moderate amount of blue light to green light to produce white light. In this study, we have successfully demonstrated the enhancement of the light extraction efficiency of YAG:Ce phosphor substrate using a simple imprint process. Spin-on-glass materials were used to fabricate a pattern on the surface of a phosphor substrate, and nano- and micro-scale patterns were formed to test the performance according to the size of pattern. The light extraction efficiency of the phosphor substrate with a micro-cone pattern increased by 33.2% compared with the flat phosphor substrate.
