摘要：
The CaZrO3:Gd3+ phosphor has been prepared by the solution combustion process. The phosphor was well characterized using x-ray diffraction, scanning electron microscopy, diffuse reflectance, electron paramagnetic resonance (EPR), and photoluminescence techniques. Upon UV light excitation (273 nm), the phosphor exhibits an ultraviolet B emission at 312 nm, which is ascribed to 6P7/2 → 8S7/2 transition of Gd3+ ions. EPR analysis of the sample confirms the presence of Gd3+ in the CaZrO3 matrix.
