  • Beta-Cesium Cadmium Silicon Sulfide Compound, Beta-Cs2CdSi4S10 Nonlinear Optical Crystal and Preparation Methods and Applications Thereof
    Publication number: 20260139409
    Abstract: The present invention provides a ?-cesium cadmium silicon sulfide compound, a ?-Cs2CdSi4S10 infrared nonlinear optical crystal, as well as their preparation methods and applications. The ?-cesium cadmium silicon sulfide compound has a chemical formula ?-Cs2CdSi4S10 and a molecular weight of 755.04. The ?-Cs2CdSi4S10 infrared nonlinear optical crystal belongs to the tetragonal crystal system, its space group is I-4, and its unit cell parameters are: a=8.4233(7) ?, c=14.6136(12) ?, and the unit cell volume is 1036.86(19) ?3. The present invention adopts a vacuum packaging method to prepare a ?-Cs2CdSi4S10 infrared nonlinear optical crystal. By using the kurtz-berry method, it was found that the frequency doubling effect of ?-Cs2CdSi4S10 crystal is approximately 1.1-1.2 times that of AgGaS2(AGS). By using the UV-visible diffuse reflection, it was found that the ?-Cs2CdSi4S10 crystal has the crystal bandgap of 4.21 eV, the UV cutoff edge of 254 nm, and the infrared transparency range greater than 13 ?m.
