该文报道在约798NM的半导体激光泵浦下,TM3+,YB3+共掺五磷酸盐非晶的蓝光发射.激光被样品吸收而直接激发TM3+离子至3F4能级.从TM3+向YB3+的能量传递,接着从YB3+向TM3+的能量传递,把TM3+离子激发至1G4能级.分析表明,声子在上转换过程中起了很大作用.“,”We report the blue upconversion luminescence of Tm~3+? and Yb~3+? codoped non?crystal pentaphosphate pumped by～798nm laser diode.The samples were directly excited to ????3F?4? level of Tm~3+? ion.Two energy transfer processes between Tm~3+? and Yb~3+? contribute mainly to the population of ????1G?4? level of Tm~3+?.Phonon plays an important role in the upconversion process.??
