White-Light Emission From GaN-Based TJ LEDs Coated With Red Phosphor

We report the fabrication of white light-emitting diode (LED) lamps by coating red phosphor onto the green/blue dual-color tunnel-junction (TJ) LED chips. For the dual-color TJ LED chips without phosphor coating, it was found that electroluminescence intensity of the green peak increased faster than...
