Description
Summary:In view of the contradictory reports of various investigators, the mass effect in radiation-induced lyoluminescence has been reinvestigated using a photon-counting technique. It is seen that the mass effect is present in both the disaccharide materials investigated, viz. sucrose and trehalose dihydrate. A likely cause of the effect may lie in the free radicals getting quenched in solution due to molecular aggregation at larger masses when the recombined nonradical product (due to radical-radical interaction) increases. This results in a decrease in LL yield with an increase of solute mass.
