在不添加其它模板剂下,利用甘氨酸与氧化钕直接水热反应制备出直径在200～300 nm,厚度为50～100 nm的NdOHCO3盘状结构.研究了各种实验参数,如反应温度、时间、前驱体的量以及表面活性剂的影响,初步探讨了这种形貌结构的生长机制.另外,实验表明通过延长反应时间或者添加表面活性剂聚乙烯吡咯烷酮(k-30),盘状结构能够组装形成新颖的三维结构.经适当煅烧后,这种盘状结构可以原位转化为六方晶相的Nd2O3,这为制备特殊结构和形貌的Nd2O3提供了一条简单而有效的途径.产物的光致发光光谱表明,这种盘状以及组装结构的产物都具有较好的荧光性质,与以往报道不同是,其在450 nm处有个较强宽的发射峰,这可能与其特殊的形貌有关. Without any addition of template agent, glycine and neodymium oxide were directly hydrothermally reacted to form disk-shaped NdOHCO3 with a diameter of 200-300 nm and a thickness of 50-100 nm. Various experimental parameters such as reaction temperature, time , The amount of precursors and the influence of surfactants, the growth mechanism of this topography was also discussed.In addition, experiments show that by prolonging the reaction time or adding the surfactant polyvinylpyrrolidone (k-30), the discoid structure can Assembled to form a novel three-dimensional structure.After proper calcination, this discoid structure can be transformed into hexagonal phase Nd2O3 in situ, which provides a simple and effective way for the preparation of special structure and morphology of Nd2O3. The results of luminescence spectra show that the products of this discoid and assembled structure have good fluorescence properties. Compared with the previous reports, they have a stronger emission peak at 450 nm, which may be related to their special morphology .
