Upconversion Luminescence from Sol-Gel-Derived Erbium- and Ytterbium-Doped BaTiO<sub>3</sub> Film Structures and the Target Form
Sol-gel technology has attracted attention in the fabrication of diverse luminescent materials and thin film structures, with forms that range from powders to microcavities. The optical properties of sol-gel-derived structures depend on the sol composition, deposition, and heat treatment conditions,...
