Abstract

Anionic surfactant-AOT-microemulsions-assisted formation and evolution of PbWO₄ nanostructures with bundles rodlike, ellipsoidlike, and spherelike prepared at different media conditions were studied by powder X-ray diffraction pattern, field emission scanning electron microscopy, and transmission electron microscopy. The possible mechanisms for the formation of PbWO₄ samples in series of microemulsion systems were discussed. Various comparison experiments show that several experimental parameters, such as the AOT concentration, the water content, and reaction temperature play important roles in the morphological control of PbWO₄ nanostructures. Room-temperature photoluminescence of PbWO₄ samples with different morphologies has also been investigated and the results reveal that all these samples showed similar features with emissions at 480 ∼ 510 nm but different luminescence intensity.
