Abstract

The existing mechanisms proposed to explain the phosphorescence of SrAl 2 O 4:Eu 2+,Dy 3+ and related phosphors were found to be inconsistent with a number of important experimental and theoretical observations. We formulated a new mechanism of phosphorescence on the basis of the facts that the d or...
