DOI: 10.1007/s40042-020-00040-8
Abstract: We investigated the substitution-site dependence of the emission properties of the Ho3+ and the Yb3+ co-doped AHfO3 (A = Ca, Sr, and Ba) perovskite series using ultraviolet (UV) and near-infrared (NIR) photoexcitation. We measured the X-ray diffraction… read more here.
