稀土离子掺杂锆酸钙纳米晶的制备及发光性质
Preparation and Luminescence Properties of Rare Earth-Doped Calcium Zirconate Nanocrystal
摘要
Abstract
The CaZrO3 nanocrystal with a perovskite structure and the CaZrO3 samples doped with different mole fraction of Eu3＋ and Dy3＋ were prepared by sol–gel method at 700 ℃ and under a short calcining time.The luminescent properties of products were inves-tigated.The results indicate that the Eu3＋-doped samples（Eu3＋：CaZrO3） exhibit strong orange-red light emission from 590 to 630 nm.Furthermore,the luminescent intensity of the Eu3＋：CaZrO3 sample doped with 5% in mole Eu3＋ reaches the maximum value.The Dy3＋-doped sample（Dy3＋：CaZrO3） shows strong yellow and blue light emissions in 575 nm and 485 nm respectively.The optimal doping quantity of Dy3＋ is 2.0% in mole and the concentration quenching of the 2.0%Dy3＋：CaZrO3 sample is not obvious.The CaZrO3 samples co-doped with Eu3＋,Dy3＋exhibit the same luminescent feature with the Eu3＋-doped sample,while the luminescence intensity of the sample occurs fluorescence quenching with the doping quantity of Dy3＋ increased.关键词
