采用高温煅烧法制备了Er3+/yb3+共掺的氟氧玻璃陶瓷新材料(41.2SIO2-29.4Al2O3-17.6nA2CO3-11.8lAf3-0.5Erf3-2.5ybf3),并制作了透明带柄微球.提出了用锥光纤微球耦合系统研究Er3+/yb3+共掺的氟氧玻璃陶瓷材料发光特性的新方法.它具有所需激发光功率低、制备简便和便于测试的特点.用锥光纤作为耦合器将976 nM激光高效耦合入微球,并将产生的荧光和激光耦合出微球输到光谱分析仪,测量到了强的522,545和657 nM上转换荧光,也测到Er3+产生的1562 nM激光振荡光谱图.分析了Er3+/yb3+共掺氟氧玻璃陶瓷微球中Er3+上转换发光的机理、发光效率高的机理,分析了在氟氧玻璃陶瓷微球中产生激光振荡阈值比在SIO2基质微球中高的机理.We prepare Er3+/Yb3+co-doped oxyfluoride glass ceramic samples by high temperature calcination method(41.2SiO2-29.4Al2O3-17.6Na2CO3-11.8LaF3-0.5ErF3-2.5 YbF3), and also fabricate transparent microspheres each with a handle.We propose a new method of studying the luminescent properties of Er3+/Yb3+co-doped oxyfluoride glass ceramic with the tapered fiber-microsphere coupling system.The method has characteristics such as low excitation optical power, easy preparation and testing.We couple the 976 nm laser into the microspheres with the coupler of optical tapered fiber, then the fluorescence and laser are connected to spectrum analyzer with the optical tapered fiber.The strong up-conversion fluorescences at 522, 545 and 657 nm are obtained, and the laser oscillation spectra generated by Er3+ions at 1562 nm are also measured.The up-conversion luminescence mechanism of Er3+, the mechanism of high luminescence efficiency in Er3+/Yb3+co-doped oxyfluoride glass ceramic microsphere, and the mechanism of higher laser oscillation threshold in the oxyfluoride glass ceramic microsphere than in the SiO2matrix microsphere are all analyzed
