摘要

采用化学浴沉积法，在不同的沉积时间制备了PbS薄膜。薄膜具有结构、光学和电学特征。采用化学还原法制备了PbS纳米粒子和Cu掺杂PbS纳米粒子。这些纳米颗粒具有结构和光学特性。以PbS薄膜为例，观察了带隙随生长时间的变化。掺杂改变了PbS纳米颗粒的带隙。

Comparison of Growth and Characteristics of PbS Thin Films and PbS Nano Materials

PbS thin films are prepared via chemical bath deposition process at different deposition time. Films are characterized structurally, optically and electrically. PbS nanoparticles and Cu doped PbS nanoparticles are grown by chemical reduction route. These nanoparticles are characterized structurally, optically. The change in band gap with growth time is observed in case of PbS thin films. Doping changes the band gap for PbS nanoparticles.
