Abstract

For the first time the nanosecond kinetics of luminescence decay from high-lying strongly quenched levels of the Ns³⁺ - ion in LaF₃, SrF₂, CaF₂, and LiYF₄. laser crystals versus energy gap (ΔE), temperature, and concentration was measured by direct nanosecond laser excitation as well as direct recording of luminescence by a statistical single-photon counting technique with a time resolution of up to 0.3ns.
