| 英文摘要 | This paper studied the de-sensitization effect of Pr3+ and Ho3+ to Er3+:2.7 mu m emission. Results show that both Pr3+ and Ho3+ are effective de-sensitizers, while great differences exist between them because of their non-phonon and phonon assisted energy transfer (ET) mechanisms. Ho3+ depresses the 2.65 mu m emission while Pr3+ strengthens it greatly. ET coefficient indicates that Pr3+ performs ten times higher I-4(13/2) depletion ability than Ho3+. In Er/Ho glasses, about 1/10 energy back transfers to I-4(13/2) level, which partially counterweights the depopulation of I-4(13/2) level. The high absorption cross section of Ho3+ is the reason for the larger I-4(11/2)-> I-5(6) ET coefficient. Line strength and spontaneous radiation probability of I-4(11/2)-> I-4(13/2) transition enhance moderately in E, E/H and E/P order, proving that the de-sensitizers promote the 2.7 mu m transition positively. Long lifetime of Ho3+ :I-5(6)/I-5(7) brings many problems, such as energy back transfer and strengthened upconversion, which also implies that the interactions of the particles obstruct the effective I-4(11/2)-> I-4(13/2) transition correspondingly.
