摘要
针对采用FTIR方法在宽波数范围内测得不同样品的发射光谱在强度上难以做定量比较的困难,提出了一种简便可行的校正方案,即通过计算发射谱仪器函数来进行强度校正;对其可行性、限制因素及注意事项进行了详细讨论.以一组覆盖宽波数范围的样品为例用此方案测量校正了室温下测得的光荧光谱,并对校正前后的结果进行了比对分析,获得了与实际符合的结论.结果表明采用FTIR测量方法并结合适当的校正方案可以获得宽波数范围内的有效发光强度信息.
Abstract
To compare the actual luminescence intensity of different samples acquired in a wide wave number range using FTIR emission spectroscopy, a feasible and convenient correction scheme of calculated emission spectroscopy instrument function was proposed. The feasibility, limitations and matters need attention were discussed in detail. Based on those schemes, the luminescence intensities of a group of photoluminescence samples cover a wide wave number range have been corrected and compared with original data. Consistent results were gained. The validity of the schemes was confirmed.
