Abstract
Sol-gel process is shown as a promising synthetic route to develop the 3D photonic crystals doped with the optically active terbium. Using silica and Tb-doped titania sols the colloidal crystal with photonic stop band ranging from 480 to 550 nm have been developed, thus fitting the 5D4 yields 7F6 and 5D4 yields 7F5 transition of Tb3+ ions. Pronounced inhibition of optical transitions of Tb3+ ions was observed. The structures fabricated are considered as promising probes to examine the influence of photonic stop band on modification of the spontaneous emission spectra of phosphors.
