Eu3+,Ce3+共掺硼硅酸锌玻璃的发光性能及能量传递
Spectral Properties and Energy Transfer of Zinc Borosilicate Glass Doped with Eu3 +, Ce3 +
摘要
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-→F1 ,5DO→7F2 and 5D0→7F3 of Eu3 + . The maximum emission wavelength is 617 nm, corresponding to D0→7F2 of Eu 3+. It is also found in the 450 nm wavelength of the emission peak of Ce +,corresponding to 5D→ F1(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.关键词
