Abstract

This paper demonstrated that the luminous efficacy of the YAG-based white light-emitting diode was improved from 74.3 to 83.7 lm/W with substitution of 0.1 mol Si4+ for Al3+ while the color rendering index was improved from 67.1 to 79.2 with substitution of 0.2 mol Al3+-O 2- by Si4+-N3- under 350 mA.
