One example is that the thermoluminescent behaviors in the afterglow luminous material are not been quite convinced or confirmed. This study uses UV and PET resin as matrix to combine with afterglow phosphors to form patches for the required experimental tests. It is found that to put the material in low temperature can preserve light energy for further usage, such behavior can be perform best with the case to drop down to 0℃ for 40 minutes and increases up to 50℃ later on. The increasing rate of light intensity can be as high as 921.43% in such case. The total light energy in the material is about 12-14 (cd/㎡×minute) regardless of how to change the temperature during the test. In order to accelerate the aging phenomenon in the patch material, this study UV light as well as heat to conduct the experimental tests. By using the samples with UV and PET resins respectively and with various thicknesses, the test result shows that the use of UV resin can be outperform PET in terms of UV as well as heat resistance, and the difference may reach as high as 100 times between them.
