The effect of charge compensation on the luminescent properties of Lu3MgyAl5−x−ySixO12:Ce3+ (x = 0–2, y = 0–2) phosphor. The emission color tuning in Lu3MgyAl5−x−ySixO12:Ce3+ (x = 0–2, y = 0–2) phosphor. The relationship between luminescent intensity and absorptivity of Ce3+ in Lu3Mg2Al3−xSixO12:Ce3+ (x = 0–2) phosphor. The luminescent properties of warm white LEDs fabricated by combining single orange phosphor with blue LED chips.
