Flavonol dye molecules in zeolite beta nanocrystals for biodiagnostic applications
Colloidal zeolite Beta nanocrystals with a Si/Al ratio of 18.5 were prepared via mild hydrothermal synthesis. The zeolite Beta nanoparticles were highly uniform in size, had a mean diameter of 100 nm, built with nanosized crystals and exhibited both micro- and mesoporosity. A calcination treatment was developed to produce template-free zeolite Beta nanocrystals with sizes and crystalline structure similar to the original zeolite Beta nanoparticles. Flavonol dye molecules were loaded in the calcinated zeolite Beta nanoparticles. Zeolite Beta nanoparticles were characterized extensively at each step of the process by complementary techniques such as X-ray diffraction, scanning electron microscopy, dynamic light scattering, nitrogen sorption, elemental analysis, static fluorescence and Raman analysis. A comprehensive study of the structure-photophysical property relations of the dye loaded zeolite Beta nanoparticles is presented
