LaOF:Eu3+ nanocrystals: Hydrothermal synthesis, white and color-tuning emission properties

Uniform LaOF and LaOF:Eu3+ nanocrystals of the γ-form have been successfully synthesized under mild conditions via a facile hydrothermal method followed a heat treatment of their bastnaesite-type precursor (LaCO 3F). The synthetic details, investigations into the phase purity and the presence of the oxocarbonate anion CO32- proven by IR measurements and EDX, as well as X-ray powder diffraction data, are given. Photoluminescence (PL) and cathodoluminescence (CL) spectra were utilized to characterize the luminescence properties of the LaCO3F:Eu 3+ and LaOF:Eu3+ samples. Under ultraviolet light excitation, the LaCO3F:Eu3+ precursor shows an orange emission of Eu3+ (dominated by 5D0 → 7F1), while the product of heat treatment, LaOF:Eu 3+, shows the characteristic emissions of Eu3+ ( 5DJ → 7FJ′J, J′ = 0, 1, 2, 3 transitions). Under the excitation of UV and low-voltage electron beams, the emission color (including white) of LaOF:Eu3+ can be tuned by adjusting the doping concentration of Eu3+. The corresponding luminescence mechanisms have been discussed in detail.
