Tunneling luminescence in long lasting afterglow of SrAl2O4:Eu,Dy

Virginija Liepina, Donats Millers, Krisjanis Smits 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 Eu2+ creation – the thermally … Continue reading Tunneling luminescence in long lasting afterglow of SrAl2O4:Eu,Dy
