| Research Abstract |
The novel pseudo-binary alloy system (1-x)ZnO-x(AgGaO2)1/2i s demonstrated by rf-magnetron sputtering using mixed powders of ZnO and β-AgGaO2with various mixing ratio as target materials. The energy band gap of ZnO is decreased with the increasing the AgGaO2concentration, and it reaches to 2.55eV (485nm). This alloy system is non-toxic unlike the previous reported alloy, i.e, ZnO-CdO, then this is suitable for the practical applications of ZnO in visible light region.
