Özet

Gd2O3 nano-powders doped with Er3+ and Yb3+ were synthesized using the combustion method. X-ray diffraction and the scanning electron microscope techniques were used to estimate the crystalline sizes and the morphologies of the materials. The Scherer calculation were employed to estimate mean crystalline sizes. The crystalline sizes were found to be < 100 nm. The down- and up-conversion emission properties of the materials have been studied using the laser spectroscopy technique. Results showed that the 1.5 μm emission of the Er3+ ions broadened with increasing Yb3+ dopant ions. The n-shape pumping power dependency of the up-conversion emission was observed. The formation of the new emission bands and the un-expected production of white light emission with increasing pumping power were observed. The color quality parameters of obtained visible emission were also measured.
