Low-temperature hydrothermal synthesis and structure control of nano-sized CePO4†
Abstract
The nanostructured CePO4 with hexagonal and monoclinic phases were controllably synthesized through a hydrothermal route at a low temperature of 100 °C by simply varying the reactant PO4/Ce molar ratio. By analyzing the synthesis procedure and product structures, the formation mechanism of the CePO4nanostructures was proposed. The luminescent properties of CePO4 with different structures and morphologies have been studied and compared. The obvious blue shift of the strongest excitation peak of the monoclinic CePO4 compared with the hexagonal CePO4 could be observed in their
