Abstract
An erasable and rewritable electron-trapping optical-storage material SrS:Eu, Sm was synthesized. Using the SrS:Eu, Sm-PMMA film, the image-recording experiment was performed. After the picture information is written on the film by the frequency doubled (532 nm) output of a Nd:YAG laser, a clearly discernible red image can be created by using 1.064 nm laser output of proper intensity (0.1 mJ/cm2) to irradiate the film. The written information can be maintained for tens of days in darkness, and one can write, read, and erase the information almost innumerable times.
