<正>A new organic-inorganic hybrid material,which shows photo-induced reduction of refractive index as well as volume contraction,is prepared using a sol-gel method.This material is coated on a Si substrate by spin-coating to manufacture film.After irradiated by ultraviolet(UV) light with a deuterium lamp for 5 h, the thickness of film decreases largely by 55%,and the refractive index of film changes from 1.484 to 1.445 at 550 nm.The film's optical thickness exhibits an exponential change with the increasing irradiation time.Futhermore.the photo-patternning of the organic-inorganic hybrid film without any further process (wet etching and thermal curing) is performed utilizing the volume contraction on UV-light irradiation. This film has potential applications for fabrication of patterned filter array and apodizing filter by direct light writing,and also demonstrates good temperature stability and immunity to visible light exposure. 相似文献

p-block metal composite oxides Sr1.36Sb2O6 and Sr2Sb2O7 synthesized by a hydrothermal method as photocatalysts in the degradation of tetracycline hydrochloride under UV light irradiation have been extensively studied.The effects of synthesis conditions on the photocatalytic activity were discussed.The Sr1.36Sb2O6-100°C-24 h-5 and Sr2Sb2O7-150℃-24 h-2 samples prepared under optimal conditions exhibited remarkably different photocatalytic activities.The essential factors influencing the difference of photocatalytic performance were revealed.The results showed that the different photocatalytic activities observed for Sr1.36Sb2O6and Sr2Sb2O7 could be attributed to their different electronic and crystal structures.Our work will provide a new perspective for the screening and design of p-block metal composite oxide photocatalysts to enhance the removal of organic pollutants in the environment. 相似文献
