abstract = "We report the effects of temperature, radiation and inter-particle distance on thin films of CdTe nanoparticles. Temperature cycling thin films between 293K and 358K resulted in a shift of 10nm in photoluminescence wavelength and a loss in emission intensity. Thermally activated trap states cause the nanoparticles to emit at different wavelengths at different temperatures. Small amounts (1 hour) of UV irradiation enhance emission from the thin films leading to higher energy wavelengths and increased intensity. Longer (4 hour) exposure to UV radiation reverses these effects and causes deterioration of the luminescence. Increasing the number of layers in a thin film results in a red-shift in the photoluminescence spectra. The inter-particle distance is decreased increasing the opportunity for inter-particle energy transfer.",
