Abstract

The conditions of synthesis and luminescence characteristics of composites Al₂O₃:Cr³⁺/NaAl(MoO₄)₂:Cr³⁺ obtained from molybdate high-temperature solutions have been studied. The influence of the impurity Cr³⁺ ions on crystallization regions in the molten system Na-Al-Mo-O has been detected as a key factor of composite formation. The luminescence emission spectra of the composite exhibit two narrow lines at 692 nm (Al₂O₃:Cr³⁺) and 740.5 nm (NaAl(MoO₄)₂:Cr³⁺), which indicates that both components of the composite are doped with chromium.

Cr(III)掺杂氧化铝/钼酸盐复合材料的合成与发光研究

研究了钼酸盐高温溶液制备的Al2O3:Cr3+/NaAl(MoO4)2:Cr3+复合材料的合成条件和发光特性。杂质Cr3+离子对Na-Al-Mo-O熔融体系结晶区域的影响是复合材料形成的关键因素。复合材料的发光发射光谱在692 nm处(Al2O3:Cr3+)和740.5 nm处(NaAl(MoO4)2:Cr3+)表现出两条窄谱线，表明复合材料的两组分都掺杂了铬。
