摘要
This article reports a novel blue emission in a series of Ca12Al10.6Si3.4O32Cl5.4:Ce3+ phosphor under excitation in the near-UV wavelength range. This phosphor was prepared using the combustion method. Here, the Ce3+ emission band is observed over a broad range of 380-550 nm, under 365 nm excitation, and is due to 5d-4f transition. The effect of a Li+ charge compensator on the emission properties of the phosphor was also investigated for the first time. X-Ray diffraction confirmed the phase purity of the synthesized phosphor. The surface morphology and elemental composition of the phosphor were studied using scanning electron microscopy and energy-dispersive X-ray spectroscopy.
