Abstract The photoluminescent phosphor materials nowadays are extremely important source of light to fulfill the technological demand over the conventional light source for eco-friendly environment. This review brings the morphological and optical properties of the chemically engineered rare earth doped photoluminescent materials at one platform. The recent developments have been incorporated and different processes involved in the morphological changes of these materials are discussed. The optical properties of different mono-, di- and tri-rare earth doped phosphors have been analyzed and evaluated using various sensitizers and surface modifiers. The photoluminescence intensity of the materials is greatly affected by changing the morphology of the phosphors via some sensitizers and surface modifiers. The large photoluminescence intensity thus obtained has been summarized due to change in the morphology. The future aspects of change in the morphological properties of the chemically engineered rare earth doped phosphors have been also proposed.

化学工程稀土掺杂荧光粉材料形态变化研究进展

摘要 光致发光荧光粉材料是满足传统光源环保技术需求的极其重要的光源。这篇综述在一个平台上介绍了化学工程稀土掺杂光致发光材料的形态和光学特性。最近的发展已被纳入，并讨论了这些材料的形态变化所涉及的不同过程。已经使用各种敏化剂和表面改性剂分析和评估了不同的单、二和三稀土掺杂磷光体的光学特性。通过一些敏化剂和表面改性剂改变磷光体的形态，极大地影响了材料的光致发光强度。如此获得的大光致发光强度已归结为形态的变化。还提出了化学工程稀土掺杂磷光体形态特性变化的未来方面。
