Dynamic Processes in the Line Shift and Linewidth of CaF₂ and CsCdBr₃ Doped with Er³⁺
(University of Canterbury. Physics & Astronomy, 2012)
The linewidths and line positions of 4I15/2 to 4I13/2 absorption transitions of trivalent erbium in CsCdBr₃ and CaF₂ were measured as a function of temperature from approximately 10 K to 300 K. By comparing the temperature ...
Two-Colour Excitation of Impurity Trapped Excitons in Wide Bandgap Insulators
(University of Canterbury. Department of Physics and Astronomy, 2013)
Impurity trapped excitons (ITEs) occurring in divalent ytterbium doped calcium and strontium fluoride crystals have been investigated by exploiting the radically different radiative decay rates of the lowest exciton state ...
