The four multi-metal sulfides Cu5FeS4, BaCu2S2, CuGd2S4, and CuAlS2are prepared by ultrasonic atomization and coprecipitation with Fe(NO3)3, Al(NO3)3, Ba(NO3)2, Gd2O3, Cu(NO3)2 and Na2S as raw materials. The phases of multi-metal sulfides are investigated by X-ray powder diffraction. The morphology of the multi-metal sulfides are observed by scanning electron microscope. The absorption and transmittance of the multi-metal sulfides in state of sol from visable light to near infrared wavelength are recorded. The results indicate that the four multi-metal sulfides are of high absorbance for near infrared light, while high transmittance for visible light. It suggests that the nano multi-metal sulfides with such special absorbing characteristics is proposed to be applied in design for novel solar heat shielding.
