A room temperature spectroscopic investigation on KYF4:1.25 at%Pr3+ is presented. The effects on the optical properties of the multisite-disordered nature of the sample are studied and discussed. In particular we report on the broadening of the 3PJ absorption lines, at 10 and 300 K, and the 450–770 nm emissions as a function of observation and pump polarization. The evidence of a peculiar difference between emission under polarized excitation, parallel or orthogonal to the c axis, is shown. The 3P0 lifetime was 45 ls in agreement with that measured in other fluoride hosts

Abstract
A room temperature spectroscopic investigation on KYF4:1.25 at%Pr3+ is presented. The effects on the optical properties of the multisite-disordered nature of the sample are studied and discussed. In particular we report on the broadening of the 3PJ absorption lines, at 10 and 300 K, and the 450–770 nm emissions as a function of observation and pump polarization. The evidence of a peculiar difference between emission under polarized excitation, parallel or orthogonal to the c axis, is shown. The 3P0 lifetime was 45 ls in agreement with that measured in other fluoride hostsFile in questo prodotto:
