Here, we report the unusual behavior shown by the PbS samples prepared using a multilayer deposition approach by chemical solution deposition method. Thin samples were prepared by depositing several films at different deposition conditions on glass substrates. X-ray diffraction showed that final multilayer samples showed a peculiar variation. Even when they showed well defined structure the intensities of the peaks do not correspond to those of the initial films.
