摘  要:通过关注这几年发光材料的发展，我们可以发现在发光材料中掺杂稀土的研究是发光材料研究发展的主流和重点方向，近年来稀土发光材料的用途十分广泛，在生活中电子发展，节能照明等都会用到发光材料，另外人们也发现稀土发光材料在医疗，探测技术等方面拥有巨大的潜力，因此也收到了人类科学研究的关注。中国在稀土应用方面的研究中，发光材料占据了最主要的地位。
在Y2O3纳米发光材料掺杂稀土可以使其具有优秀的发光性能。 在本文中,我们详细的解释了在Y2O3发光材料中掺杂稀土的发光机理和发光性能。本文中所采用高温焙烧方法可以用来合成多种结构和特征的Y203:Tb3+荧光材料。在实验中通过改变焙烧时间、焙烧温度以及掺杂稀土元素浓度的不同等方面，可以实现对Y203:Tb3+荧光材料的结构及形貌的产生一定的控制。35384

Preparation of Luminescent yttrium Oxide by High Temperature Calcination
Abstract: In the development of rare earth functional materials， especially the rare earth luminescent materials particularly attract sb．'s attention． Rare earth because of its special electronic structure，and has general elements incomparable spectroscopic properties，rare earth luminescent covering almost the entire solid state lighting category， as long as it comes to the light， almost inseparable from the rare earth．Rare earth element atoms have not filled by shielding the external 4f5d electronic configuration， it is abundant electron energy levels and long-lived excited state，energy transitions channels up to more than 20 million，can produce a variety of radiation absorption and emission，constitute a broad luminescent and laser materials． With rare earth separation and purification technology of progress，and the relevant technical promotion，rare earth luminescent materials research and application has grown significantly．Light is the most prominent rare earth compound optical， magnetic three funtion，by people of great concern． Results of the analysis of the world and the United States 24 kinds of rare earth application in the field of consumer，rare earth luminescent materials of output and price are at the forefront．Study on the application of rare earth application in the field of consumer， rare earth luminescent materials of output and price are at the forefront．
Light is the most prominent rare earth compound optical，magnetic three funtion， by people of great concern excellent luminescent properties and luminous efficiency．In this paper，we described a system of luminescent properties n the application of rare earth application in the field of consumer，rare earth luminescent lumine scent materials．This method calcined at high temperature，Y2O3：Tb3+ fluorescent materials with different structures and characteristics of the synthesis．By adjusting the calcination time， temperature and doping ratio parameters， the initial realization of Y2O3： fluorescent material， the structure and morphology control．
