【摘要】本文研究了ErYb共掺的氟氧化物玻璃 (ErYb:FOG)、氟化物ZBLAN玻璃和五磷酸盐非晶在 966nm半导体激光激发下的直接上转换敏化发光现象。发现有丰富的上转换发光现象 ,这是由于样品中Yb3 + 的浓度很高 ,Er3 + Yb3 + ,Yb3 + Yb3 + 离子之间的相互作用和能量传递作用都很强造成的。研究发现ErYb :FOG玻璃的直接上转换增敏发光比磷酸盐大 1 0 0～ 1 0 0 0 0 0倍 ;而很有趣的结果在于氟氧化物玻璃的直接上转换增敏发光与ZBLAN玻璃接近 ;这对于提高频率上转换的综合性能是很有意义的。更多还原

【Abstract】 This paper investigates the direct upconversion sensitization luminescence of the ErYb co-doped oxyfluoride glass (ErYb:FOG), fluoride glass (ErYb:ZBLAN) and pentaphosphate noncrystalline (ErYb:PP) excited by a 966 nm diode laser. The splendid upconversion luminescence phenomenon is found. It is resulted from that the Yb 3+ concentration in rather high, the energy transfer among Er 3+-Yb 3+ and Yb 3+-Yb 3+ ions is rather strong. An important fact is found that the direct upconversion sensitization luminescence of ErYb:FOG is about 100-100 000 times greater than that of ErYb:PP. And meanwhile it is interesting that the upconversion luminescence intensity of ErYb:FOG is near to that of ErYb:ZBLAN. It is significant to enhance the comprehensive level of upconversion luminescence.更多还原
