Thermoluminescence from Silicon quantum dots: A model study

Most of the bulk materials start showing fascinating behaviors as their size is reduced to nano level. The ability to emit light as a consequence of absorption of energy (luminescence) is one of these exotic behaviors. There are different types of luminescence observed from nano silicon. Thermoluminescence (TL) is the emission of light from an insulator or semiconductor when it is heated. It is the thermally stimulated emission of light due to absorption of energy from radiation. So, there is a direct relationship between temperature (due to absorption of heat or radiation) and the TL intensity. We develop a model for calculating the TL intensity as a function of temperature and dot size. Our results are quite new and require future studies
