摘要
本文研究以化学式简单且易于合成的硼酸钆为基质,选择拥有不同发光特性的 Ce3+、Tb3+、Eu3+作为被掺杂离子,试图通过不同的合成方法制备出纳米与非纳米尺度的稀土掺杂GdBO3发光材料,一方面研究纳米与非纳米材料在发光性能上的差异,另一方面优选出最具实际应用价值的合成方案.对于常规(非纳米)样品,我们以稀土氧化物为反应物原料,使用高温固相法进行合成;对于纳米样品,我们则以稀土硝酸盐为反应物原料,使用水热法进行合成.随后,我们利用 X-射线粉末衍射技术对所制获的样品的物相纯度进行表征,同时测定其光致发光性能.
Abstract
This study investigates the synthesis,characterization,and testing of rare earth-doped GdBO3 luminescent materials using borate-based GdBO3 as a matrix with simple chemical formula and easy synthesis.Different doping ions,namely Ce3+,Tb3+,and Eu3+,with distinct luminescent properties,are selected to explore the nanoparticle and non-nanoparticle scale synthesis methods for the rare earth-doped GdBO3 luminescent materials.The objective is twofold:firstly,to investigate the differences in luminescent performance between nanoparticle and non-nanoparticle materials,and secondly,to identify the most practical and valuable synthesis approach.For conventional(non-nanoparticle)samples,rare earth oxides are used as reactant materials,and high-temperature solid-state synthesis method is employed.For nanoparticle samples,rare earth nitrates are used as reactant materials,and hydrothermal synthesis method is utilized.Subsequently,X-ray powder diffraction is conducted to characterize the phase purity of the synthesized samples,and their photoluminescent properties are evaluated.
