In this paper we report the synthesis of CdS:Cu nanoparticles by chemical precipitation. The structure and thermoluminescence (TL) properties of the particles were studied. TL glow curves and kinetic data, for example activation energy, order of kinetics, and frequency factor of the nanoparticles, were determined for different UV exposure times. TL glow curves were recorded for different doses of UV exposure time at a heating rate of 10 ° s−1. TL glow peaks were observed at 241.2, 252.3, and 275.3 °C when the particles were exposed to UV for 5, 10, and 15 min. Kinetic data for the synthesized nanophosphor CdS:Cu were calculated by use of the peak-shape method; trap depth was also calculated, by use of different formulae. XRD results showed the sample has a cubic structure. The average particle size was 35 nm. The Miller indices were also obtained.
