Abstract

Blue and ultraviolet upconversion (UC) emissions at 455 and 363 nm were observed from Tm³⁺ doped fluoroindate glasses pumped with a 650 nm pulsed dye laser. The temporal behavior of the fluorescence signal originate from the ¹D₂ manifolds was studied for different Tm³⁺ concentrations. The fluorescence measurements revealed the origin of the UC process as well as allowed to quantify the interaction between Tm³⁺ ions. The results indicate that a two-step absorption process is responsible for the UC emission and the dominant interaction contributing for ET among of active ions is the dipole-dipole interaction.
