摘要

The Mn-doped ZnS nanoparticles with T_d~2 - F43m cubic structure and an average crystalline size of about 16 nm were synthesized using the hydrothermal method at 220℃ for 15 h from Zn(CH_3COO)_2 (0.1M), Mn(CH_3COO)_2 (0.01M), and Na_2S_2O_3 (0.1 M) as the precursors. The appearance of characteristic photoemission bands of Mn~(2+) (3d~5) ions at 390, 430, 467, and 493 nm in the photoluminescence excitation spectra while monitoring the yellow-orange band at 585 nm showed that the Mn~(2+) (3d~(10)) ions substituted for Zn~(2+) (3d~(10)) ions in ZnS matrix and caused the ferromagnetism of Mn-doped ZnS nanoparticles. The dependence of photoluminescence, photoluminescence excitation spectra, and magnetization curves on Mn content and the wavelength of excitation radiation were reported.
