In this paper, the thermal and mechanical properties were investigated for the fabricated specimens of SL5510 in the different UV post-cure time. This may instruct us to employ better the fabricated parts of SL5510.展开更多

The system selects the emitting LED, which is economical and practical as a light source. The experiment of the emission and excitation optical spectrum, decay curve of fluorescence and residuals for several sensitive materials confirms the match of Y2O2S:Eu using the light source and the feasibility of the system. The rare earth material Y2O2S:Eu is selected as the material candidate for being the most sensitive.展开更多
