tm3+, yb3+ and tm3+/yb3+ doped lavo4 nanostructures were synthe-sized for the first time by using the hydrothermal method with the aid of la(ch3co2)3 as lanthanum source in presence of oleic acid as surfactant. the products were characterized by x-ray diffraction (xrd), scanning electron microscopy (sem), transmission electron microscopy (tem), photoluminescence (pl) spectroscopy and uv–vis di...
