Abstract
Styryl dyes and compositions which exhibit superior two-photon absorption cross-sections and are useful in two-photon pumped cavity lasing, two-photon pumped upconversion lasing, optical power limiting, optical power stabilization, optical signal reshaping, and infrared beam detection and indication are disclosed. Also disclosed are multiphasic nanostructured composites which include a glass having pores, an optically active coating material on the pore surface, and a polymeric material in the pores. These composites are useful in producing multifunctional optical materials, such as broadly tunable lasers. Methods for killing cells and viruses using a photosensitizer and a two-photon upconverting dye are also described. These methods are especially useful to kill cells and viruses in biological materials, such as in photodynamic therapy of tumors and cancers or blood purification protocols. Media and methods for recording data in a three-dimensional matrix which includes a plurality of dye molecules is also described. The data storage methods and media have approximately 10.sup.12 volume elements per square centimeter, and each of the volume elements can store a single bit, digital information, or analog information. The data storage methods and media of the present invention are particularly useful for storing or archiving a series of two-dimensional black and white or color images, such as frames of a movie.
