Lanthanide ions doped CaMoO4 with pie-like microstructures were synthesized by a hydrothermal method using phenol-formaldehyde resin (PF) as an inducer. The results of powder X-ray diffraction showed a tetragonal phase of both undoped and Ln(3+)-doped CaMoO4. The microscopical characterization technology revealed the formation process of the pie-like microparticles. As a morphology inducer, the PF molecules played an important role in the formation of phase structure. The as-obtained materials were characterized using different spectroscopic techniques including FT-IR, Raman spectrum, and PL. The emission color can be easily turned by adjusting the relative doping concentrations of lanthanide ions.
