Thermoluminescence and induced phosphorescence in irradiated doped PMMA

Thermoluminescence (t.l.) is reported for doped poly(methyl methacrylate) (PMMA), irradiated by X-rays and u.v. light. The results are correlated with those we previously reported for induced phosphorescence in the same system. These luminescence results are accounted for in terms of transient speci...

Description
Summary:Thermoluminescence (t.l.) is reported for doped poly(methyl methacrylate) (PMMA), irradiated by X-rays and u.v. light. The results are correlated with those we previously reported for induced phosphorescence in the same system. These luminescence results are accounted for in terms of transient species which have been reported for irradiated PMMA and which were detected by e.s.r. and optical absorption techniques. The transient species responsible for t.l., and induced phosphorescence, appears to be the same, namely a radical derived from PMMA. A brief outline is given of the production of such transients and their subsequent reactions in the post-irradiation period. The energy transfer processes involved are discussed in terms of an energy level diagram.
