The Synthesis of a High Yield PbSe Quantum Dots by Hot Solution Method

초록

Colloidal solutions of crystalline PbSe nanoparticles have been synthesized by hot Solution chemical process using PbO in oleic acid and tributylphosphine (TBP) bonded selenium. The use of TBP as a capping agent along with oleic acid gives a very good yield (around 10% at 180 degrees C) with an average diameter of particle of about < 6.6 nm. The effects of temperature on size and production yield of PbSe quantum dots are studied. X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM) and UV/VIS/NIR absorption spectroscopy were used to characterize the samples.
