Abstract

In this paper we present the spectroscopic properties of YLF:Yb:Tm:Nd system identifying the most important processes that lead to the thulium blue up conversion emission, under excitation around 792 nm. Analysis of the 475 nm emission for the samples with different concentrations of Nd³⁺ ions showed that energy transfer between Nd³⁺ and Yb³⁺ is the main mechanism and responsible for an enhancement in up conversion.
