摘要

稀土掺杂是提高光电功能材料性能的重要途径. 把稀土掺杂铁电材料与稀土发光相结合, 还可拓展出铁电材料的新性能, 比如, 选择合适的稀土元素掺入钛酸铋铁电材料, 可使之在保持较好的铁电性能的同时, 又显示良好的发光性能. 近年来, 这类在氧化物铁电材料中由于稀土离子掺杂产生光致发光特性的研究引起了人们的关注, 有望研制集成发光铁电器件. 本文简要介绍了稀土发光铁电材料的研究状况, 重点介绍我们在稀土发光铁电薄膜方向的研究进展. 我们的研究表明, 稀土掺杂钛酸铋铁电薄膜同时具有较好的发光特性和铁电特性, 这与其独特的成分构成和层状钙钛矿结构密切相关; Eu³⁺离子荧光结构探针可以为进一步研究Eu³⁺掺杂铁电薄膜材料的结构与性能关系提供新思路; 在某些铁电薄膜(如Pr离子掺杂的x(K_1/2Bi_1/2)TiO₃-(1－x)(Na_1/2Bi_1/2)TiO₃薄膜等)中掺入稀土离子后, 稀土离子的发光可用于检测铁电薄膜中是否存在准同型相界; 将ZnO纳米材料和金、银纳米颗粒与掺铕钛酸铋薄膜复合, 可显著增强稀土发光.

Abstract

Rare earth doping is an important method to improve the properties of optoelectronic functional materials. Combining rare earth doping ferroelectric materials and rare earth photoluminescence can create new functional properties of ferroelectric materials. For example, choosing and using an appropriate rare earth element to be doped into a bismuth titanate ferroelectric material, the bismuth titanate will exhibit good photoluminescent properties as well as ferroelectric properties. Recently, photoluminescence properties originating from rare earth ions in oxide ferroelectric materials have attracted much attention for possible integrated photoluminescent ferroelectric device applications. In this paper, we briefly review the research status and progress of photoluminescence in rare earth photoluminescent ferroelectric materials, and we place the emphasis on our own research work in photoluminescent ferroelectric thin films such as (Bi,Eu)₄Ti₃O₁₂, (Bi,Er)₄Ti₃O₁₂, and codoped bismuth titanate thin films, and nanocomposite (Bi,Eu)₄Ti₃O₁₂ ferroelectric thin films. Our results show that the rare earth doped bismuth titanate ferroelectric thin films exhibit good photoluminescent and ferroelectric properties due to unique compositions and layered perovskite structure, that the Eu³⁺ fluorescent structure probe can provide a new path for further studying the relationship between structure and property of Eu-doped ferroelectric thin films, that the rare earth photoluminescence can be used to examine the existence of morphotropic phase boundary in certain ferroelectric thin films such as Pr-doped x(K_1/2Bi_1/2)TiO₃-(1－x)(Na_1/2Bi_1/2)TiO₃ thin films, and nanocomposite materials of ZnO nanomaterials, and that Au nanoparticles, Ag nanoparticles with Eu-doped bismuth titanate exhibit obviously enhanced photoluminescent properties.
