Red upconversion luminescence has been introduced in functional semiconductor SnO2 by doping rare earth ions Er3+ and Yb3+ and using 980 nm diode laser as pump source. High temperature solid state reaction leads to incorporation of trivalent lanthanide ions in SnO2. For high concentrations of lanthanide doping, partial reduction of Sn4+ to Sn2+ occurs for charge compensation making the material system SnO2-SnO alloy. Upconverting SnO2 exhibits paramagnetic characteristics with magnetization increasing with introduction of trivalent rare earth ions Er3+/Yb3+.
