| 摘 要： | 采用高温液相法制备了50ZnO-30SiO2-20B2O3∶Eu3+,Ce3+玻璃。测试了样品的激发光谱和发射光谱。结果表明:在紫外光激发下,该玻璃可以发出明亮的红色光。其中580 nm,593 nm,617 nm,655 nm和706 nm波长处的发射峰分别对应于Eu3+的5D0→7F0,5D0→7F1,5D0→7F2,5D0→7F3和5D0→7F4跃迁发射,其中5D0→7F2跃迁发射强度最大,同时发现在450 nm处存在Ce3+的5D→2FJ(J=7/2,5/2)特征发射峰。首次发现在该发光玻璃50ZnO-30SiO2-20B2O3∶Eu3+,Ce3+中存在着Ce3+→Eu3+能量传递现象,其中Ce3+起敏化作用。

| Abstract: | The 50ZnO-30SiO2-20B2O3 ∶ Eu3+,Ce3+ is prepared by conventional high-temperature liquid-phase method and their excitation and emission spectra were recorded.The results indicate that the glass can emit red light under the excitation of UV.The glass show emission with peaks at 580 nm,593 nm,655 nm and 706 nm separately due to transitions of 5D0→7F0,5D0→7F1,5D0→7F2 and 5D0→7F3 of Eu3+.The maximum emission wavelength is 617 nm,corresponding to 5D0→7F2 of Eu3+.It is also found in the 450 nm wavelength of the emission peak of Ce3+,corresponding to 5D→2FJ(J=7/2,5/2).It demonstrated that exist energy transfers from Ce3+ to Eu3+ in the system,in that the Ce3+ ions act as sensitizers. |
