Abstract

Detailed room temperature absorption and emission spectra and the dynamics of the upconversion energy transfer were investigated in Yb, Ho codoped KYF₄. It was found, in the concentration range studied, that the energy transfer rate from Yb³⁺ to Ho³⁺ ions is linearly dependent on Ho³⁺ concentration. The back transfer from Ho³⁺ to Yb³⁺ ions was demonstrated and the transfer rate was found to be superlinearly dependent on Yb³⁺ concentration. Discussions are presented on the optimization of Yb³⁺ and Ho³⁺ concentrations for the potential use of Yb, Ho codoped KYF₄ as an upconversion green laser.
