Application of (Ca1-xSrx)LaGa3S6O:Eu2+ phosphor in white light-emitting diode fabrication

An alternating sequence of Ca_1-xSr_xLaGa₃S₆O:0.05Eu²⁺ phosphors was produced using high-thermal and solid-state reactions. It has outstanding excitations at the range between 350 and 500 nm suitable for the closeultraviolet or GaN-based blue light-emitting diode light emitting diode (LED) chips. These phosphor peaks have a blue shift between 560 and 540 nm when the Sr concentration (x) rises. The Sr content (x) can be modified to produce an illumination with a color between yellow and green. As a result, we can conclude that solid solutions Ca_1-xSr_xLaGa₃S₆O:0.05Eu²⁺ are excellent for use in manufacturing white LEDs. Our data may become valuable for producers in the task of making white light emitting diode (WLED) devices suitable for them.
