| 摘 要： | 通过改变氧化钇薄膜中掺杂稀土元素的种类,来控制发光薄膜的荧光发射波长.利用电化学沉积法制备稀土掺杂氧化钇荧光薄膜.电化学沉积法制备的薄膜结晶效果好,掺杂离子分布较均匀,且不需要高温高压或者真空条件,成本很低.所制备的Y2O3:Ln荧光发光薄膜经XRD分析具有立方晶体结构；不同稀土掺杂的氧化钇呈现出不同的表面形貌；掺杂的Ln离子均匀地分布在薄膜中,经测试所有的Y2O3:Ln荧光发光薄膜都显示出较强的发射强度,且发光波长随着掺杂离子的不同而不同:Y2O3:Er3+发绿光,Y2O3:Ce3+发黄绿光,Y2 O3:Sm3+发蓝光,Y2O3:Pr3+发橙光.因此,电化学沉积法可用于制备具有不同发光波长的氧化钇荧光薄膜.

| Abstract: | By controlling the doping rare-earth(RE) elements in the Y2O3 thin film,the emission wavelength of fluorescence can be controlled.The Y2O3: Ln(Er3+,Ce3+,Sm3+,Pr3+) thin film phosphors(TFP) are synthesized by electro-deposition method.The prepared Y2O3: Ln(TFP) have cubic crystal structure as indicated by XRD;Y2O3 TFPs doped with different rare-earth(RE) elements present different surface morphologies.The doped Ln ions(Er3+,Ce3+,Sm3+,Pr3+) are uniformly distributed in the thin film phosphors.All the Y2O3: Ln... |
