title = "Free volume related fluorescence properties of electron irradiated chalcone doped PMMA films",
abstract = "Effect of electron irradiation on free volume related fluorescence properties of chalcone doped Poly(methyl methacrylate) (PMMA) composite films have been studied using Positron Annihilation and Fluorescence spectroscopic techniques. In this polymer composite, enhancement of fluorescence at lower doses and reduction at higher doses has been observed under electron irradiation. From Positron annihilation studies suggests that at lower doses of irradiation induced crosslinking which affect the free volume properties and inturn hinders the chalcone molecular rotation. At higher doses chain scission process affect matrix relaxation. Under the restricted condition the chromophore molecules likely to emit enhanced fluorescence and its mobility is directly related to the free volume around it.",
