本文考察了10种国产纤维素膜用于多环芳烃固体基质室温磷光(SS-RTP)的可行性。实验表明:MN-C和MN-P两种型号的微晶纤维素膜用于多环芳烃的SS-RTP是适宜的。阴离子交换纤维素膜、CM-纤维素膜和聚酰胺-6膜也能诱导出多环芳烃的RTP来,但其性能逊于前两种。故本文应用MN-C和MN-P两种微晶纤维素膜基质考察了五种多环芳烃的RTP特征,并建立了它们的SS-RTP新方法。并与用滤纸作基质的实验结果进行了比较,表明两种新的固体基质的RTP性能优于滤纸基质。
This article examines the feasibility of 10 domestic cellulose membranes for PAH solid substrate phosphorescence (SS-RTP). Experiments show that: MN-C and MN-P two types of microcrystalline cellulose membrane for polycyclic aromatic hydrocarbons SS-RTP is appropriate. Anion-exchange cellulose membranes, CM-cellulose membranes, and polyamide-6 membranes were also able to induce polycyclic aromatic hydrocarbons (RTPs), but their performance was inferior to the first two. Therefore, two kinds of microcrystalline cellulose film substrates, MN-C and MN-P, were used to investigate the RTP characteristics of five PAHs and their new SS-RTP methods were established. Compared with the experimental results of using filter paper as matrix, the RTP performance of the two new solid substrates is better than that of filter paper.
