Preparation and Luminescent Properties of Ca0.8Zn0.2TiO3:Pr3+ Phosphor via Precursor

采用前驱体微波加热法、电阻加热法和传统的高温固相法等不同方法制备了Ca0.8Zn0.2TiO3:Pr3+荧光粉,以 TG-DSC、XRD、荧光光谱和粒度分析为表征手段,比较了不同方法制备Ca0.8Zn0.2TiO3:Pr3+的发光性质.XRD测定结果表明, 前驱体微波加热法和电阻加热法制备的样品可使反应温度低200℃,但材料的晶体化程度不高.TG-DSC的测定结果表明,前驱体在加热达到700℃以上才完全失重.荧光光谱和粒度分析的测定结果表明,与传统的高温固相法制备的荧光粉相比, 前驱体微波加热法和电阻加热法制备的荧光粉具有发光增强和颗粒细小均匀的特点,但微波加热法更为简单.
