Abstract: Red-emitting phosphor is a crucial luminescent material in white LED lighting applications
It is important to effectively improve the properties of red phosphor for preparing high color rendering
index, low temperature, and high power white LED. Synthetic method of phosphor is one of the factors
to influence the surface morphology and optical properties of red phosphor. In this paper, based on the
tungstate and molybdate red phosphor system, the application and research on synthesis technique in
recent years were analyzed. The present research situation for the synthesis method of tungstate and
molybdate red phosphor system was introduced in detail, such as high temperature solid phase method
sol-gel method, precipitation method, hydrothermal method, spray pyrolysis, and combustion method
The processes and characteristics of different preparation methods and the influence on the
performance of phosphor were discussed, and the future development direction, such as computer
simulation, modern technology assistant, mechanism and so on, was prospected
