Abstract :
Phosphor-free monolithic high-efficiency tunable white LEDs are realized on ternary InGaN substrates. This proof-of-concept study demonstrates that high quantum efficiency and stable white color emission are achieved by using ternary substrates and correctly-engineered device structures.
