Luminescent materials play an important role in making solid state white light-emitting diodes (w-LEDs) more affordable home lighting applications. To realize the next generation of solid-state w-LEDs with high color-rendering index (CRI), discovery broad band and long emission wavelength luminescent is urgent mission. Regarding this, oxonitridosilicate Y3Si5N9O a nitrogen concentration should be suitable host material to achieve those promising properties. In this work, phase-pure...
Abstract Laser‐driven solid‐state lighting with super‐brightness and compactness is recognized as a promising alternative to white light‐emitting diodes. However, it quite difficult achieve laser‐driven warm light long‐term stability due the shortage of robust orange‐ or red‐emitting laser phosphors.

Thermally robust phosphor ceramics are an ideal color converter for high-power laser lighting applications. However, high-quality white light is difficult to achieve due the absence of green and red emission materials. AnY3Al5–xGaxO12:Ce3+ (YAGG:Ce3+) ceramic can emit light, while strong oxidizing atmosphere needed suppress Ga evaporation during high-temperature fabrication process, which seriously decrease luminescence efficiency. To enable green-emitting YAGG:Ce3+ material application, we...
