Assembly of PbTe/Pb-based nanocomposite and photoelectric property

PbTe/Pb-based nanocomposite was assembled by combining the regular PbTe/Pb nanostructure and the Zn(x)Mn(1−x)S nanoparticles; the photoelectric property of the nanocomposite was measured in situ. The results showed that the through current of the nanocomposite had an obvious increase compared to that of the individual PbTe/Pb nanomaterial under the same irradiation conditions. The improvement of photoelectric performance would be attributed to the synergistic effect brought by the incident light and exciting light of the Zn(x)Mn(1−x)S nanoparticles. The result implied that the underlying mechanism could be used to improve the performance of nano-optoelectronic devices and the light-use efficiency of solar devices.
