Description

Emission spectra of Ho3+-doped YVO4 crystals are studied in the visible and infrared spectral regions. Besides the emission bands at 544 nm and at about 1950 and 2017 nm due to Ho3+, we observed a broad emission band at 610 nm at low temperatures like 15 K in the highly doped crystals with the Ho3+ concentrations of more than 0.5 mol%. The excitation band for this broad emission is located at 390 nm which is near the edge of band gap of the crystal. It is suggested that the 610 nm band is attributed to defects related to oxygen vacancies around V4+ ions. (copyright 2007 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim) (orig.)
