Abstract

The layer structure of gradient refractive index was proposed to improve the extraction efficiency of white LEDs based on quantum dot phosphor. Ray-tracing simulation shows that the extraction efficiency increases by 7∼14% with new layer structure of refractive index difference of 0.15 compared to the remote phosphor structure.
