研究目的
Investigating the synthesis, structural, and photoluminescence properties of (SrTiO3)1-x – (YInO3)x: Eu3+ perovskite type red phosphors for potential applications in white light-emitting diodes (WLEDs).
研究成果
The synthesized Sr0.95-xEu0.05YxTi1-xInxO3 phosphors exhibit orange-red emission suitable for solid-state lighting applications, with enhanced luminescence due to YInO3 incorporation. The phosphors show high absorption at 394 and 464 nm, making them promising for WLEDs. The study highlights the importance of host material selection and dopant concentration in optimizing phosphor performance.
研究不足
The study is limited to the synthesis and characterization of (SrTiO3)1-x – (YInO3)x: Eu3+ perovskite type red phosphors. Potential areas for optimization include further investigation into the luminescence quenching mechanism and the exploration of other dopants or synthesis methods to enhance luminescence efficiency.
