“…When g-irradiated microcrystals are dissolved in a fixed volume (3 mL) of distilled water, initially the LL intensity increases with time, attains a maximum value I m at a particular time tm, then decreases and finally disappears. This is supported by equations (1), (5) and (6).…”

“…However there are a number of factors that influence the light yield during the dissolution of γ ‐irradiated alkali halides in water, and which have not been investigated in detail. Various studies have been undertaken to understand the mechanism of LL (5). The parameters that influence the LL intensity are, for example, grain size, mass of the irradiated alkali halide, pH of the solvent, temperature of the solvent, irradiation dose, etc.…”

The temperature and mass dependence of lyoluminescence intensity of γ-irradiated colored potassium chloride powder have been studied using a photomultiplier tube connected to an x-y recorder. The peak lyoluminescence intensity increases with increasing amount of solute added up to 50 mg and then tends to saturate. The lyoluminescence (LL) glow curves with mass of KCl microcrystals show that initially the LL intensity increases with time and then decreases exponentially with time. The decay time consists of two components for all the masses. The dependence of decay time, especially the longer component on mass, has been investigated. The temperature dependence of LL intensity shows that initially the peak LL intensity increases with temperature up to 60°C, and then decreases with further increase in temperature. The decay time tends to decrease with increasing temperature. An explanation for the experimental results has been attempted.

“…When an emission center responsible for the light emission does not originate from the dissolving solid, the phenomenon is called extrinsic lyoluminescence (ELL) [2,3]. However, when the emission is based on a sequence of chemical reactions the phenomenon can also be called chemiluminescence (CL).…”

“…However, there are a number of factors that influence the light yield during dissolution of γ -irradiated alkali halides in water, and which have not been investigated in detail. Various studies have been undertaken to understand the mechanism of LL (Reynolds 1992). The parameters that influence the LL intensity are, for example, grain size, mass of the irradiated alkali halide, pH of the solvent, temperature of the solvent, irradiation dose, type of impurity etc and requires detailed investigation for the development of LL dosimetric materials (Chandra et al 1997).…”
