in this paper photoluminescence ( pl ) spectra and time-resolved spectra were applied to study inas quantum dots . and we have got some significative results 本论文较为深入地研究了量子点的光致发光谱(pl)和时间分辨谱(ts),并取得了一些有意义的结果。
the key technology of measuring time-resolved spectrum is to design and make the special light beam modulator that is used to the time-resolved spectrum detecting 瞬态时间分辨谱测量方法的关键技术:设计和研制了专用于时间分辨谱采集分析的光束调制器。

(2 ) . inas quantum dots and wetting layer were studied and compared by using photoluminescence and time-resolved spectrum . luminescent mechanics model of inas quantum dots and wetting layer were presented, and it explained our results well (2)采用光致发光谱及时间分辨谱对inas量子点及浸润层的发光性质开展研究和对比,提出单层inas量子点和浸润层发光的机理模型,较好地解释了实验结果。
in this method of measuring temperature, when the measuring results of time-resolved spectrum have been completed, computing the fit spectrum of corresponding planck bold-radiation with least duple multiply theory, the temperature is measured 温度拟合方法的主要思想:获得光谱的时间分辨测量结果后,用最小二乘法原理计算热辐射谱(主要在可见光区)拟合得到相应普朗克黑体辐射加线,并解析其温度。
