Abstract
- Abstract: Y2.9Ce0.1Al5O12 (YAG:Ce3+) phosphors with 80±5nm are successfully prepared by hydrothermal processing followed by the post annealing process in Ar/15%H2 atmosphere. The emission intensity of the as-prepared YAG:Ce3+ nano-phosphor is as high as with that of the ∼15μm YAG:Ce3+ commercial phosphor. Meanwhile, the YAG:Ce3+ nano-phosphors prepared in both Ar/15%H2 and air atmosphere show same stable emission intensity under continuous irradiation of blue excitation light, although this photobleaching behavior is easily observed for YAG:Ce3+ nano-phosphors in the literatures. Photobleaching is probably suppressed by complete crystallinity due to the post annealing process and solid morphology due to the hydrothermal process in the present work. [Copyright &y& Elsevier]
