PbSe nanorods were synthesised through chemical bath deposition at room temperature (303K) and at elevated temperature 365K. XRD shows the synthesised PbSe were polycrystalline having cubic rock salt type structure. The most preferential growth direction was along (200) direction. SEM exhibits the shape and size oriented growth morphology. The optical measurements show excitonic absorption at 740nm and blue emission in the range 363nm- 397nm which are attributed to the strong quantum confinement of PbSe nanostructures.
