Abstract

Summary form only given. Lithium niobate (LiNbO/sub 3/) exhibits excellent electro-optical, acousto-optical and nonlinear optical characteristics, and therefore, it has been widely used for both bulk and integrated optics. As no work has so far been reported on the up-conversion emission study of sol-gel derived Er/sup 3+/ doped LiNbO/sub 3/ we have therefore taken up the present work for the first time. Photoluminescence spectra in the visible wavelength range were measured on a Fluorolog system attached with a phosphorimeter by using xenon flash cw lamp. A strong upconversion emission at 543 nm has been observed.
