Study on the synthesis and optical properties of YIn1-xMnxO3 by N/S doping

The solid solution of YIn1-xMnxO3 shows intense blue colors as well as excellent properties. In this paper, N- and N/S- doped YIn1-xMnxO3 samples are successfully prepared by the high-energy ball milling method with hexamethylenetetramine (C6H12N4), urea (CH4N2O) and thiourea (CH4N2S). The X-ray diffraction patterns of samples with various anion doping all show single phase and the oxidation state of Mn are maintained as +3. In C6H12N4 treated YIn0.7Mn0.3O3, N is in the interstitial site while in CH4N2O treated YIn0.7Mn0.3O3, N exists in both interstitial site and substitution site. In CH4N2S treated YIn0.7Mn0.3O3, both S and N are in the substitution site and interstitial site. Due to the anion doping by N and S, the optical properties of the samples are modified and analyzed.
