•Near-spherical CaSiO3 nanocrystals were synthesized via a hydrothermal method.•The effect of calcination temperature on crystalline phase formation was discussed.•Optical properties of trivalent ions doped CaSiO3 nanocrystals were investigated.•Tunable luminescence of CaSiO3:Tb3+, Eu3+ can be achieved by a simple method.
CaSiO3:RE3+ (RE3+ = Eu3+, Sm3+, Tb3+, Dy3+) nanocrystals were prepared by facile hydrothermal method with further calcinations. The crystal structure and the effects of annealing temperature on phase transition have been characterized by X-ray diffraction (XRD). The photoluminescence (PL) and PL excitation (PLE) spectra were used to characterize the optical properties of all samples. The effect of Eu3+ and Sm3+ doping concentrations on the luminescent intensity were also investigated in details, respectively. Moreover, the luminescence colors of the Tb3+ and Eu3+ co-doped CaSiO3 samples can be tuned by simply adjusting the relative doping concentrations of the rare earth ions under a single wavelength excitation, which might find potential applications in the fields of light display systems and optoelectronic devices.
