| 中文摘要 | uniform laof and laof : eu3+ nanocrystals of the.-form have been successfully synthesized under mild conditions via a facile hydrothermal method followed a heat treatment of their bastnaesite-type precursor (laco3f). 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 : eu3+ and laof : eu3+ samples. under ultraviolet light excitation, the laco3f : eu3+ precursor shows an orange emission of eu3+ (dominated by d-5(0) -> f-7(1)), while the product of heat treatment, laof : eu3+, shows the characteristic emissions of eu3+ (d-5(j) -> f-7(j') j, j' = 0, 1, 2, 3 transitions). under the excitation of uvand 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. |
