The principles, characteristics, and measurement methodology of photochromism of plastic ophthalmic lenses are briefly introduced and discussed. The factors influencing measurement variation and accuracy, including the preconditioning process, measu
Lit-doped HoPO4 powders with a pure tetragonal phase are successfully synthesized by the co-precipitation method. It exhibits an obvious color change under sunlight and tri-phosphor fluorescent light illumination. The introduction of Lit ions into Ho
Fulgide, a kind of thermally irreversible photochromic compound, can be used for polarization holographic recording owing to its photoinduced anisotropy and photochromic property under the irradiation of linear polarization light. In this letter, a n
A series of diarylethene derivatives with two-photon absorption was designed and synthesized. The nonlinear properties of two-photon induced fluorescence of the compounds were examined. A strategy for the design of molecules with large two-photon abs
The implementation of photoinduced linkage isomerism in molecular-based optical materials represents a promising approach for the synthesis of high-contrast, high-resolution photosensitive materials that are necessary for high-density (holographic) d
The broadband photochromic effect on undoped and rare-earth-doped lead lanthanum zirconate titanate (PLZT) ceramics was studied under the illumination of ultraviolet light at 360 nm. The photocarriers’ trapping and detrapping processes of thermal dis
