| Popis: | Laser stealth absorption material Sm2O2S was successfully synthesized by a solid state flux fusion method. The phase composition, morphology and optical property were investigated by X-ray diffraction with Rietveld structure refinement, scanning electron microscopy, thermogravimetry–differential scanning calorimetry and ultraviolet–visible spectrophotometer. The results showed that Li2CO3/Na2CO3 composites were the optimal flux for the crystal formation. Na2CO3 plays an important role during the reaction. With the increase of temperature, crystal structure became regular. The hexagonal shape powders could be achieved above 1100 °C. Furthermore, the as-prepared Sm2O2S powder had an intense absorption around 1.06 μm, causing by electron transitions from ground state 6H5/2 to excited state 6F9/2. The study indicated that Sm2O2S can be a promising 1.06 μm laser absorption material. |
