摘 要：A novel 1064 nm laser stealth absorbent of Sm2O2S was prepared by flux method.The effects of different calcining temperatures and fluxes on the reflective property of Sm2O2S were investigated.The phase composition,morphology,and reflectivity of the powders were character-ized by X-ray diffraction（XRD） ,scanning electron microscopy（SEM） ,and ultraviolet-visible spectrophotometer（UVPC） .The results showed that pure phase of Sm2O2S could be obtained with Na2CO3 as flux above 950oC,and the reflectivity decreased with the calcination temperature increasing.Compared with other samarium compounds,the reflectivity at 1064 nm of Sm2O2S was the lowest.Different fluxes had great impact on the phase composition,particle morphology,and reflectivity of the products.In short,Sm2O2S was suitable as a kind of absorbent against 1064 nm laser.
