A two-step reaction method was used to prepare superfine LaPO₄:Ce,Tb phosphor particles under two set of conditions. The
crystallinity and particle morphology of the product were characterized by using XRD, SEM and particle size analysis, and
decay lifetime was investigated as a function of preparation conditions. Results highlighted that an appropriate preparation
process leads to less-aggregated LaPO₄:Ce,Tb phosphor with greatly improved decay lifetime. |
