| 摘 要： | NH4MO(OH)HCO3(M=Al3+， Cr3+) precursors were synthesized by a co-precipition method with the solutions of mixed nitrates as starting materials and ammonium bicarbonate as precipitator. The precursors and powders sintered at various temperatures were characterized by thermogravimetry/differential thermal analysis(TG/DTA)， infrared spectroscopy(IR)， X-ray diffractormetry(XRD)， transmittion electron microscopy(TEM). The luminescent spectra of Cr3+∶Al2O3 nano-powder was measured. The XRD results show that the pure-α-Al2O3 phase can be obtained at 1 200 ℃. TEM analysis indicates that the nano-powders about 20～30 nm are well-dispersed and less-aggregated. Spectral analysis demonstrates that the sample has good photoluminescence.
