title: Size-dependent temperature sensitivity of photoluminescence peak position of CdTe quantum dots.
abstract: The size dependence of the temperature coefficient (sensitivity) of the photoluminescence (PL) peak position of CdTe quantum dots stabilized by thioglycolic acid in aqueous solution has been investigated. Temperature sensitivity increases as the average radius of CdTe quantum dots decreases. This must be taken into account in the design of solar light concentrators and light-emmiting diode-monitors as well as other technologies in which a fine tuning of the light emission is important.
