This study is devoted to multiexcitation of phosphors in LED devices. A new model of
double and triple excitation of phosphors in UV chip and double excitation in blue chip was
proposed and discussed. The suitable phosphor candidates were synthesized and investigated.
A LED devices with an n-UV Ga(In)N chip as well as blue InGaN chip and multiexcited
phosphors were designed and constructed. These LEDs show better quantum yield of green
and red phosphors, higher total brightness and improved color rendering index (CRI). |
