摘要

We measured the 1.5 mum emission spectra corresponding to I-4(13/2) --> I-4(15/2) transition of Er3+ in borosilicate glass within the temperature range from 11 to 300 K. The spectral components emitting from the lowest and upper Stark levels of I-4(13/2) state were distinguished by analyzing the spectra with normalized area. The effect of optical properties of the spectral components on the 1.5 mum emission bandwidth is investigated. The results indicate that to search for a host with higher spontaneous emission probability of the upper Stark levels of I-4(13/2) state for Er3+ ions is very important to broadening of the 1.5 mum emission band. An equivalent model of four-level system is presented and applied to explain the spectral shape and temperature characteristics of the 1.5 pin emission band. (C) 2004 Elsevier B.V.
