摘要	High-quality SrAl(12)O(19):Pr(3+) nanodisks and nanoplates were fabricated via a new processing technique based on a modified polymer steric entrapment method. Serious agglomeration and large particle size distribution of final products, which usually occurred in the conventional method, were eliminated completely. The effects of new synthetic processes on the morphology, crystallization, and yield of products and the relevant mechanisms were discussed. As far as we know, SrAl(12)O(19):Pr(3+) nanodisks with mean diameter similar to 60 nm and thickness between 5 and 10 nm were successfully synthesized for the first time by this low-cost technique. The new synthetic method may provide a general route to synthesize other refractory mixed-oxide nanocrystals. Photon cascade emission involving transitions (1)S(0)-(1)I(6) followed by (3)P(0)-(3)H(4) in SrAl(12)O(19):1% Pr(3+) nanodisks was investigated. Size-effect-induced blue shift of the 4f5d states of Pr(3+) was observed in SrAl(12)O(19):1% Pr(3+) nanodisks, in which the quantum efficiency was preserved, as in the bulk counterparts.
