Description

Microcrystalline undoped as well as cerium-doped lead tungstate (PbWO4) powder with different phase and shape, were successfully synthesized via a low-temperature hydrothermal method using different lead sources (lead acetate and lead nitrate) and Na2WO4 as metallic cations and distilled water as solvent. The effect of lead sources and Ce3+ doping on crystallite size and shape were investigated with XRD, SEM and TEM. The average crystallite size was found between 28 and 82 nm using the Scherrer formula. Incorporation of Ce3+ into undoped PbWO4 reduces the average crystallite size. The raspite phase of PbWO4 generates nanobelts-like structure. Photoluminescence spectra show broad blue-green emission in the 450-550 nm range and the luminescence intensity decreases with cerium doping compared to undoped PbWO4 due to the nonradiative 5d-4f transition of the excited Ce3+.
