Promising Red Phosphor Ca3Al2O6:Eu3+ For LED Solid-State Lighting Application
Abstract
Ca3Al2O6:Eu3+ phosphor has been synthesized by combustion method. The phosphors were characterized using X-ray diffraction and photoluminescence (PL) techniques. The prepared phosphors were excited by 395 nm, the PL emission observed at 616 and 594nm and intensity of 616 nm (5D0→7F2) was almost equal to 594 nm (5D0→7F1). The photoluminescence spectrum of Ca3Al2O6:Eu3+ phosphor showed the emission intensity of phosphor increased with increasing the concentration of europium. The investigated prepared phosphors are suitable for a NUV excited LED.
