ZnGa₂O₄ phosphors were synthesized from ZnO and GaO(OH) by high temperature reaction in solid state.The product was characterized by means of XRD and the emission spectrometric analysis.The results show that the pure phase of ZnGa₂O₄ was obtained when the molar ratio of ZnO to GaO(OH) was 1.2:2.The sample with n(GaO(OH)):n(ZnO)=2.0:0.9 (mole ratio) exhibits the strongest fluorescence intensity.Moreover,the product synthesized from GaO(OH) and ZnO has better property than those synthesized from ZnO with α-Ga₂O₃ or β-Ga₂O₃.
