本研究探討，將市面上常使用的綠色螢光材料(C545T)，摻雜光酸發生劑(PAG)，經由曝光過程，可以發現曝光前後，C545T材料會與光酸發生劑(PAG)產生新產物，我們可以測得不同情況下的吸收與放光光譜，如在液態溶液或在固態高分子薄膜中。
在液態溶液(THF)中，在不同濃度的C545T摻雜不同比例的光酸發生劑(PAG)，我們可以很容易觀察到其吸收與放光光譜有所改變，其中發現會隨著光酸發生劑(PAG)的濃度，而使原本的放光波段能量轉移到新產物身上，放光波段有紅外移的現象發生。
此外，在固態高分子(PMMA)薄膜中，為了避免C545T分子在溶液中的自由活動，相互碰撞，因此有消光現象，故我們將材料成膜，探討液態與固態間的光譜變化。

In this thesis , we studied the photo-chemistry between the green emitter (C545T) and the photo-acid generator (PAG) . When the sample of C545T and PAG in solutions and thin films were exposured to UV-light , we found that a new product was produced due to protonation of C545T with the acid generated by PAG . Therefore , we measured absorption and fluorescence spectra of the samples in solutions (THF) and in polymer (PMMA) thin films .
The different concentrations of C545T dopanted photo-acid generator in the solvent (THF) could increase the photo-acid generator at higher concentrations of PAG , the energy could be transferred from unprotonated to protonated . Therefore , we can easily observe the absorption and fluorescence spectra have been changed and the phenomenon of stock’s shift has been found accordingly .
At higher concentrations of C545T in solutions , also called concentrations quenching effect was observed because C545T molecules could collide each other easily that causes intensity to decrease in the solvent (THF) . In order to get rid of the collision effect , we use the samples of polymer thin films instead of solutions . The different of the change of spectra between solutions and thin films were observed and compared were also studied .
