摘要:
采用溶胶-凝胶法制备Tb3+掺杂β-Ga2O3纳米粉末.用X-射线衍射(XRD)、拉曼(Raman)、光致发光激发谱(PLE)和发光谱(PL)对其进行了一系列的表征. XRD 和 Raman 的结果表明: Tb3+离子的掺入没有改变β-Ga2O3结构.用350 nm的激发光去激发Tb3+掺杂β-Ga2O3纳米粉末,样品的最强峰在543 nm (5D4-7F5)附近,对应着Tb3+离子的绿光发射.此外,还讨论了能量传递机制.
Abstract:
Tb3+ doped β-Ga2O3 nanopowders were prepared by sol-gel method. X-ray diffraction (XRD), Raman technique, photoluminescence excitation spectra, and photoluminescence (PL) were used to characterize the nanopowders. XRD and Raman results revealed that the Tb3+ ions did not change the structure of β-Ga2O3 host lattice. When the Tb3+ doped β-Ga2O3 nanopowders were excited by 350 nm wavelength, the main emission of the samples was 543 nm (5D4 -7F5), which corresponded to a typical green emission of Tb3+ ions. In addition, the energy transfer mechanism in Tb3+ doped β-Ga2O3 nanopowders was discussed.
