文摘

1064 nm laser stealth absorbent Sm₂O₂S was prepared by solid state flux method. The effects of doping Er3+ and Tm3+ on the powder’s phase compositions and reflecting property were investigated. The phase composition, morphology and reflectivity of powders were characterized by X-ray diffraction, scanning electron microscopy and ultraviolet visible spectrophotometer (UV-3600PC). The results exhibited that doping Er3+ and Tm3+ cause no significant changes on crystal structure. However, the morphology of powders changed a lot after doping Er3+/Tm3+, which influenced on the reflecting property. Because of the characteristic absorption of Er3+ and Tm3+, the reflectivity of Sm₂O₂S powders decreased in different degrees. The doping amount of Er3+ was 15 mol%, the lowest reflectivity 0.7450 % was obtained. The optimized doping amount of Tm3+ was 10 mol% and the reflectivity was 0.7403 %.
