Abstract

Summary form only given. Using persistent spectral hole burning, rare-earth ions doped in crystalline or glassy matrices may prove useful in optical data storage. In the case of Sm/sup 2+/, persistent spectral hole burning is due to photoionization: the Sm/sup 2+/ is oxidized to form Sm/sup 3+/, and the ejected electron is trapped in the matrix. For applications, it is important to understand the trapping mechanism, to identify the nature of the traps, and to see whether they are stable at room temperature.
