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.
