文摘

PbS nanoparticles having the suitability for power semiconductor devices, were synthesized by facile, effective, and surfactant-free hydrothermal method. The effect of reaction time on the morphology, microstructure and optical properties of PbS nanoparticles was investigated. The methods of XRD, TEM, HRTEM, EDX, FTIR and UV–VIS photometry measurements were used for PbS nanoparticles characterization. The reaction time was found to have an effective role in controlling the morphology, crystallinity, crystallite size, microstrain and optical band gap of the prepared samples.
