abstract

The up-converted luminescence at 525, 550 nm and 670 nm wavelengths, as well as the ordinary luminescence near 1600 nm wavelength of the LiNbO3:Yb3+, Er3+ crystal are investigated under optical excitations at 808 nm and 980 nm. Dependencies of luminescence on intensities of optical pumping at both wavelengths are presented. The possible mechanisms of up-converted emissions obtaining as well as population mechanisms of the Er3+ ion 4I13/2 energy level in the LiNbO3 matrix are discussed.
