在真空安瓿中高温合成了二硫化铜铝（CuAlS2）粉末。x射线衍射分析表明，加热温度高于800℃的粉末为单相CuAlS2。在室温下测得的阴极发光（CL）光谱中，温度高于600℃的粉末在约1.8 eV处有一个可见光发射峰，在3.45 eV处有一个明显的紫外发射峰。在700℃加热时，粉末的紫外辐射强度最大，被认为与激子有关。
Copper aluminum disulfide (CuAlS2) powders were synthesized in an evacuated ampoule at elevated temperatures. X-ray diffraction analysis revealed that the powders heated at temperatures higher than 800oC were single-phase CuAlS2. In the cathodoluminescence (CL) spectra measured at room temperature, the powders heated at temperatures higher than 600oC exhibited a visible emission peak at approximately 1.8 eV and a distinct ultraviolet emission peak at 3.45 eV. The powder heated at 700oC showed the maximum intensity of ultraviolet emission which is considered to be associated with excitons.
