The appearance of characteristic photoemission bands of Mn2+ (3d5) 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 Mn2+ (3d10) ions substituted for Zn2+ (3d10) 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.Hong Van BuiHoang Nam NguyenNam-Nhat Hoangnhathn@vnu.edu.vnThanh Trung TruongVan Ben Pham
