摘要

Y_2.9Ce_0.1Al₅O₁₂ (YAG:Ce ³⁺) phosphors with 80±5 nm are successfully prepared by hydrothermal processing followed by the post annealing process in Ar/15%H ₂ atmosphere. The emission intensity of the as-prepared YAG:Ce ³⁺ nano-phosphor is as high as with that of the ∼15 μm 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:Ce ³⁺ 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.
