Abstract
Nano layers of PbSe have been fabricated in liquid medium via direct reaction of lead acetate and n-trioctylphosphine bonded selenium. The effect of temperature on particles diameter is studied. The scanning electron microscopy reveals that the layer-by-layer deposition has taken place with average diameter of the particle of about <20 nm. The XRD measurement shows that higher temperature is favorable for layered nanocrystals of PbSe and NIR measurement shows that absorption at 3.31 μm is due to size quantization effect thus increasing the band gap energy from 0.27 to 0.56 eV, which is the reported value for bulk PbSe.
