The time-resolved photoluminescence spectra of synthesized Cu2 O nanowires are fitted by the func-tion of exponential decay in Origin. The time-resolved photoluminescence lifetimes of the Cu2 O nanowires are obtained in the temperature region of 77-300 K.%基于用Origin软件的指数衰减拟合函数对制备得到的Cu2 O纳米线的时间分辨荧光光谱进行拟合，得到了Cu2 O纳米线在77-300 K温度范围内的瞬态荧光寿命值。
