Kopsavilkums

A long lasting (afterglowing) luminescent material SrAl₂O₄: Eu²⁺, Dy³⁺ was prepared by high temperature solid-state reaction method. The processes responsible for long lasting luminescence were studied by means of luminescence spectra, thermally stimulated luminescence and afterglow kinetics. Two processes are found to contribute in excited Eu ²⁺ creation – the thermally released electrons recombination and electron tunneling from trap to Eu³⁺. The possible scheme of long lasting luminescence mechanism is proposed.
