摘要

采用三能级系统的速率方程和功率传输方程并考虑温度对各项参数的影响，求解在不同的光纤长度和量子点掺杂浓度时，3.3 nm PbSe量子点液芯光纤的发射光谱随温度的变化。发现当光纤长度不同时，随着温度的升高，光谱的峰值位置以相近的速率发生红移，光谱的峰值强度下降。对于较长的光纤，其光强随温度升高的衰减速率较大。当掺杂浓度不同时，随着温度的升高，光谱的峰值位置以相近的速率发生红移，峰值强度以相近的速率衰减。

Abstract

Three-level system-based rate equation and power transfer equation were used to solve the temperature dependent emission spectral properties for 3.3 nm PbSe quantum dot doped liquid core fiber under different fiber length and doping concentration

considering the effect of the temperature on the parameters.It is found that the spectral peak position shifts to the red in a similar red shift rate with the temperature increasing

in the case of different fiber length. For the longer fiber

the spectral peak intensity decreases in a larger decline rate. In the case of different doping concentration

with the temperature increasing

the spectral peak position shifts to the red in a similar red shift rate

and the spectral peak intensity decreases in a similar decline rate.
