摘要：
Different chromophores were encapsulated in molecular sieves, and the optical properties were investigated. A spiropyran derivative in different faujasites, obtained by dye synthesis in the nanocages, exhibits improved properties as optical switch. By pumping of rhodamine BE 50 in AlPO4-5, synthesized through addition of the chromophore to the synthesis mixture of the molecular sieve, stimulated emission (lasing) was observed. A SO2 sensor was constructed by suspending MCM-41,containing a covalently bonded rhodamine B, in a polysiloxane film.
