Lyoluminescence and ESR correlation studies of trehalose dihydrate.

ESR studies of irradiated lyoluminescence (LL) phosphor, trehalose dihydrate showed a linear free radical growth up to a dose of 11 kGy. The LL output measured under oxygen equilibrated conditions showed an extension of the dosimetric response from 0.6 to 6 kGy. ESR spectral analysis indicates the formation of two radical species viz., 'a' and 'b' and their… (More)
