Abstract: Ce3+-doped Lutetium aluminum garnet Lu3Al5O12 phosphors were prepared by an anti co-precipitation from mixing solution of lutetium, aluminum and cerium nitrates using the ammonium hydrogen carbonate as precipitate,followed by the calcination at low temperatures. TG-DTA, FTIR, XRD, TEM and Photoluminescence were used to characterize the as-prepared phosphors. The calcining temperature has distinctly influence on the particle size and the photoluminescence of the prepared Lu3Al5O12(Ce) powders. The resulted Lu3Al5O12(Ce) powder calcined at 1000℃ for 2h has an average particle size of 30nm. And its photoluminescence is the strongest among the powders calcined in the range from 850℃ to 1200℃.

Key words: co-precipitated, Lu3Al5O12(Ce), luminescence, nanoscaled powder
