Abstract: Both particle size and morphology of cerium-doped yttrium aluminium garnet(YAG∶Ce) yellow phosphors could exert significant influence on their phtoluminescence as well as further applications. It has been demonstrated that the desired morphology is spherical with a controlled size. In this paper, progresses of morphologic and size control of YAG∶Ce phosphors by the synthesis methods, technology parameters and posttreatment techniques were summarized, the advantages and disadvantages of morphologic control measures were discussed, and the main features of regulation and control for powder morphology were concluded.

Key words: cerium-doped yttrium aluminium garnet, white LED, morphology, regulation and control
