Abstract
Absorption and emission spectral properties of GdVO 4 single crystal doped with Ho 3+ ions were investigated at room temperature. Polarized absorption cross section is calculated in the range of 400–2200 nm. Results were analyzed and parameters were calculated based on Judd-Ofelt theory, the emission spectrum shows that the emission intensity around the wavelength of 546 nm associated with transition 5S 2 → 5I 8 is much stronger than other bands in the observed range and potentially enable the green light output around this emission band in this crystal.
