早在50至60年代末,关于MnO单晶的光吸收谱就有了一些报道,并对吸收谱上出现的5个吸收带进行了分析,关于纳米MnO粉体的光吸收至今未见报道.本文作者测量了粒径为 80nm的MnO粉体在200至2500nm波长范围内的光反射谱,并对反射谱上出现的吸收带的机制进行了分析.1 试样制备和实验结果
As early as the 1950s to the late 1960s, there was some reports on the optical absorption spectra of MnO single crystals, and the five absorption bands appeared on the absorption spectrum were analyzed. The light absorption of nano-MnO powders has not been reported so far. The authors measured the light reflectance spectra of MnO particles with a size of 80 nm in the wavelength range of 200 to 2500 nm and analyzed the absorption band mechanism of the reflected spectrum.1 Sample Preparation and Experimental Results
