A photosensitive emission polymer containing trimethylolpropane triacrylate as reactive monomer, Norrish I and II photo-initiators, pentaerythritol tetrakis (2-mercaptoacetate) as photo-sensitizer, and bis (n-salicylidene-4, 4'-diaminophenyl) methane named H2L1 and Alq3 as emitters were studied in this paper. The UV-visible absorption and photoluminescence spectra were particularly employed to examine the influence of the chemical structure of photo-initiator on the emission properties of photosensitive polymer. The results show that photo-initiators, such as I369 and I907, reduced the emission intensity due to the nitrogen in their chemical structure and the UV-visible absorption overlapping with the excitation of the emitters; whereas the photo-initiators of I184, I500, I651, and BP could provide extra energy to enhance the emission intensity of H2L1 and Alq3 respectively. In addition, through the photolithography process, the resolution of photosensitive emission polymer is about 15μm for demonstration.
