Abstract

Laser time-resolved site-selection spectroscopy measurements were used to characterize the properties of Eu³⁺ ions in seven types of glass hosts including oxide glasses of lithium phosphate, lithium silicate, sodium silicate, potassium germanate, lithium borate, and europium pentaphosphate as well as the fluoride glass ZBLA. The ⁷F₀-⁵D₀ transition was resonantly excited and the results were obtained by monitoring the ⁵D₀-⁷F₀ fluorescence which has not been done in most previous work of this type because of laser scattered light. This was overcome by the use of a fast electronic shutter. Measurements were made of the spectral structure, fluorescence lifetime, inhomogeneous linewidth, fluorescence 1ine-narrowed (FLN) width, and energy transfer rate parameter as a function of host composition, temperature, and excitation position within the inhomogeneous line.
