Upconversion emission properties and un-expected white light emission from Er3+/Yb3+ doped Gd2O3 nano – phosphors
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 [...]
