The absorption spectra of dye-doped polymer thin films made from a variety of five dyes and six matrices, either organic or organomineral, are analyzed to evaluate the residual absorption in the red wavelength tail and in particular at amplified spontaneous emission (ASE) wavelengths. An absorption cutoff wavelength is defined as the extrapolated wavelength at which the absorption losses are expected to become negligible compared to the structure losses. Such absorption-spectrum-extrapolated wavelengths are compared to the ASE wavelengths and found to correlate for most of the dye-matrix couples. The propagation losses of PM597-doped organic polymers are also measured and accordingly found to increase with the glass transition temperature of the host matrix.
对由五种染料和六种有机或有机-无机基质制成的染料掺杂聚合物薄膜的吸收光谱进行了分析，以评估红色波长尾部尤其是放大自发辐射（ASE）波长处的残余吸收。吸收截止波长定义为外推波长，在该波长下，预计吸收损耗与结构损耗相比可忽略不计。将这种吸收光谱外推波长与ASE波长进行比较，发现大多数染料-基质组合都存在相关性。还测量了掺杂PM597的有机聚合物的传播损耗，结果发现其随主体基质的玻璃化转变温度而增加。
