Abstract
In the field of solid-state lighting, phosphor-in-glass composites (PIGs) containing colorful phosphors can be used to improve the spectral fixation and color rendering indices (CRIs) of phosphor conversion materials. However, PIGs using red nitride phosphors are difficult to produce because the phosphors decompose at high temperatures. Therefore, this study presents a method of producing orange–red PIGs at low temperatures (320 °C) using Y 3Al 5O 12:Ce 3+ and CaAlSiN 3:Eu 2+ phosphors based on the fluorophosphate glass matrix. Scanning electron microscopy and X-ray diffraction show that the crystalline phases of the phosphors in the PIGs remain intact and independent. The prepared samples can achieve luminescence efficiency up to 92.5 lm/W and ideal CRIs. Therefore, the proposed materials have a wide range of potential applications in high-quality lighting and displays.
