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.
