The use of thermally stimulated luminescence for rapid assessment of plasma treated particulate materials

Thermally induced light emission (luminescence) is presented as a particularly suitable tool for monitoring the level of plasma surface activation. The method is relatively fast, exhibits a surprising sensitivity and allows evaluation of even poorly defined surface, which are typical for particulate materials. The examples of three distinct materials are presented – plasma activated PET flakes, cellulose fibres pulp and Al2O3 powders.
