产品介绍 |
PbS量子点的玻尔半径较大,容易制备出具有显著量子效应的纳米颗粒。由于其优良的非线性光学性能,合适的禁带宽度,电子能带跨越900~1600nm的红外光谱区域,正好和“通讯波长”部分重叠,因而,PbS量子点在光电器件、通讯、发光二极管、太阳能电池等领域有着广泛应用。此外,PbS量子点亲水性强,生物相容性好,有望在生物和医学领域得到普及应用。我们的PbS量子点具有粒径分布窄,色彩纯度高,发射近红外光,稳定性好等优异特性,且成本低,易于大规模量产。 常用溶剂:甲苯、氯仿、正己烷,常用浓度:25mg/ml。使用前依据自己的实验需求直接加溶剂稀释即可。无须特殊处理,溶液建议于一周内使用完毕,超过一周发射峰会发生偏移。 PbS QDs have large Bohr radius with strong quantum effect. Due to its excellent nonlinear optical property, suitable forbidden band width, electronic energy band across 900~1600 nm infrared wavelength range that overlap with “communication wavelength”, PbS QDs have the potential to be used in optoelectronic devices, communication devices, light-emitting diodes, solar cells, and other fields. In addition, PbS QDs can be easily transferred into water with high biocompatibility, thus can be widely used for bio-imaging and–labeling applications. Synthesized using our proprietary unique technology, our PbS QDs have narrow particle size distribution, high color purity, near-infrared emission, and excellent stability. |
