Abstract Semimagnetic chalcogeneide Pb1-xMnxS nanocrystals were grown in borosilicate glass host and their optical, structural and magnetic properties were investigated. Transmission electron microscopy images confirms the growth of the Pb1-xMnxS nanocrystals. Uv–Vis-Nir spectroscopy measurements of these nanocrystals revealed band-gap shifting from 0.94 eV (1307 nm) to 1.12 eV (1111 nm), which was attributed to the incorporation content (x) of Mn2+ ions in the typical PbS rock salt crystal structure. EPR data shows the six hyperfine lines assigned to the Mn2+ ions incorporated into the host crystal structure of PbS nanocrystals. The Photoluminescence obtained at 20k was analyzed and shows an anomalous increase in emission efficiency considering carrier transfer for Pb1-xMnxS nanocrystals with different sizes.

热退火和 sp-d 交换相互作用对嵌入玻璃基质中的 Mn2+ 掺杂的 PbS 纳米晶体的光学性能的影响

摘要 在硼硅玻璃基质中生长半磁性硫属化物Pb1-xMnxS 纳米晶体，并研究了它们的光学、结构和磁性能。透射电子显微镜图像证实了 Pb1-xMnxS 纳米晶体的生长。这些纳米晶体的紫外-可见光-近红外光谱测量显示带隙从 0.94 eV (1307 nm) 移至 1.12 eV (1111 nm)，这归因于典型 PbS 岩盐晶体中 Mn2+ 离子的掺入含量 (x)结构体。EPR 数据显示了分配给结合到 PbS 纳米晶体主体晶体结构中的 Mn2+ 离子的 6 条超细线。分析了在 20k 下获得的光致发光，并显示考虑到不同尺寸 Pb1-xMnxS 纳米晶体的载流子转移，发射效率异常增加。
