摘要
以GaO(OH)和ZnO为原料,采用高温固相法合成了ZnGa2O4荧光粉。对样品进行了XRD及发射光谱表征。当n(Ga)∶n(Zn) =2∶1 .2时,制得的ZnGa2O4为纯相;n(Ga)∶n(Zn) =2∶0. 9时合成的ZnGa2O4的发光性能最好,以GaO(OH)和ZnO为原料制备的ZnGa2O4,其发光强度是以α- Ga2O3或β- Ga2O3为原料制备的ZnGa2O4的发光强度的 2倍。
ZnGa_2O_4 phosphors were synthesized from ZnO and GaO(OH) by high temp erature reaction in solid state. The product was characterized by means of X RD and the emission spectrometric analysis. The results show that the pure p hase of ZnGa_2O_4 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. Mo reover, the product synthesized from GaO(OH) and ZnO has better property than th ose synthesized from ZnO with α-Ga_2O_3or β-Ga_2O_ 3.
