Abstract: With the technical developments of display lighting and fluorescence labeling, the demands for the luminescent materials with advanced performance are placed on the desk of researchers. The luminescent materials with low producing cost, high efficiency and being free from pollution are still preferred by the scientists. Rare earth ions doped luminescent materials are key content in the studied scoped of optical spectroscopy. Earth ions luminescent nanomaterials became a hot issue which is concerned by the researchers. Tungstate as an important new functional materials used in various fields social life, to explore the synthesis of tungstate and the properties of tungstate materials are known as the hot areas of the field of materials. Some common preparation methods of tungstate are introduced, such as hydrothermal method, Sol-gel method, high temperature calcination, microwave solid phase synthesis method, Top seed crystal pulling method, microcontact printing route, high temperature solid phase reaction.
