Influence of Temperature on HPDLC Grating Characteristics
温度对全息聚合物分散液晶光栅形貌及电光特性的影响

Holographic gratings,using the system made of photosensitive pre-polymer monomers,nematic liquid crystal and photoinitiator mixtures,were fabricated under various curing temperatures.The samples were checked up by IR spectra,tical microscope and He-Ne laser.The results indicate that diffraction efficiencies of grating increased first,then decreased along with curing temperature hoists.These results were analyzed,and were found to have a good correlation with characteristics of system.The relation between temperature and diffraction was discussed.
