Abstract
Multicolor fluorescent containers: A silica coating procedure has been devised for the preparation of multifluorescent dye-loaded zeolite L crystals with luminescent anisotropic cores and isotropic shells. The method comprises a combination of the polyelectrolyte layer-by-layer technique and Stöber synthesis (see scheme, TEM image, and fluorescence microscopy images).
