Optical Properties and Upconversion Luminescence of BaTiO<sub>3</sub> Xerogel Structures Doped with Erbium and Ytterbium
Erbium upconversion (UC) photoluminescence (PL) from sol-gel derived barium titanate (BaTiO<sub>3</sub>:Er) xerogel structures fabricated on silicon, glass or fused silica substrates has been studied. Under continuous-wave excitation at 980 nm and nanosecond pulsed excitation at 980 and...
