High-power blue-emitting laser diodes have been applied to projectors and lighting systems as excitation sources for yellow-emitting phosphors. These phosphors must be robust and should not exhibit thermal quenching. This work developed durable eutectic phosphors with a thermal conductivity of above 20 W/m·K.
