Optical characterization of mechanically alloyed PbSnS3 nanocrystals

AIn4S6Cl (A = Rb and Cs) and Pb5Sn3Q10Cl2 (Q = S and Se): quaternary chalcohalides with mixed anionic coordination exhibit photocurrent responses

“…45 The results of the UV-vis-NIR diffuse reflectance spectra of compounds 3 and 4 show that their band gaps are 1.72 and 1.44 eV, respectively, which agree well with their black colors. These band gaps are close to those of PbSnS 3 (1.33 eV) 46 and Pb 3 S 2 Cl 2 (1.51 eV). 41 Photocurrent response and variable-temperature conductivity…”

Determining the majority charge carrier, optical and structural properties of electrochemically deposited lead tin sulfide (PbSnS) thin films

“…Solar energy fits this bill and is widely expected to continue, combined with other renewable energy sources, to replace non-renewable energy sources. However, the wide spread applications of solar cells will require dramatic decrease in cost through the use of materials that are promising, environmentally friendly and economical to replace conventional materials [1]. In recent times, the attention of researchers is focused on the large family of chalcogenides that possess very unique and interesting properties.…”
