Luminescent properties of Y3Al5O12:Ce3+ phosphor-in-glass for WLEDs.

YAG:Ce3+ phosphor-in-glass slices were fabricated and their potential applications in light emitting diodes were investigated in the present work. The optical properties of the fabricated glass slices show obvious dependence on the thicknesses and the contents YAG:Ce3+ phosphor powder in glass slices. The fabricated glass slices have excellently thermal stability, which is demonstrated by the heating experiments in the temperature range of 25–250 °C and the accelerated thermal aging experiments with 20 days. The electroluminescence of light emitting diodes was tuned by changing the thickness of glass slices and the contents of YAG:Ce3+ phosphor powders in the glass slices. The results in the present work show that YAG:Ce3+ phosphor-in-glass slices are prospective to replace the conventional epikote/silicon-based phosphor converter for the construction of light emitting diodes.
