“…Ayrıca, güneş pilleri için bir soğurucu olarak ta kullanılmaktadır [3][4][5]. PbS ince filmler, kimyasal banyo depolama (CBD), ardışık iyonik tabaka adsorpsiyonu ve reaksiyonu (SILAR), sol-jel, kimyasal buhar biriktirme, elektrodepozisyon, vakum buharlaştırma, darbeli lazer biriktirme, sprey piroliz gibi yöntemlerle üretilmektedir [6][7][8][9][10][11][12][13]. PbS ince filmleri üretmek için kullanılan yöntemler arasında kimyasal banyo depolama yöntemi, geniş yüzeylere uygulanabilmesi, düşük sıcaklıkta üretilebilmesi ve düşük maliyetli olması gibi birçok avantaja sahiptir [6].…”

In the present study, polycrystalline lead sulfide thin films have been successfully deposited on glass substrates using chemical bath deposition technique in the presence of cocamide diethanolamine. The effects of cocamide diethanolamine used in different ratios on the structural, morphological, and optical properties of PbS thin films were investigated using X-ray diffraction (XRD), scanning electron microscopy (SEM), scanning probe microscopy (SPM) and UV-visible spectroscopy analyses. From the XRD analysis, it was obtained that the crystal size of the PbS thin films decreased from 12.57 nm to 5.43 nm with the increase in the amount of cocamide diethanolamine additive. In addition, the microstrain and dislocation density values increased depending on the amount of cocamide diethanolamine additive. SEM analysis shows that cocamide diethanolamine additive affects the surface morphology of nanostructured PbS thin films. SPM analysis showed that the surface roughness values of the thin films increased with the increase of cocamide diethanolamine additive. By UV-visible spectroscopy analysis, it was obtained that the optical transmittance value of the PbS thin film increased approximately 3 times at the amount of 1% cocamide diethanolamine additive. In addition, the optical band gap values of PbS thin films increased from 1.87 eV to 2.53 eV depending on the amount of cocamide diethanolamine.

“…Several research groups have tested different dopant elements such as Ag, Al, Cu, Cd, Zn, Sb, Sn, etc. [18][19][20][21][22][23][24][25][26] for PbS, to tailor its optical and electrical properties. Despite all these efforts, doping still remains a challenging task to obtain high-quality PbS films with better optical and electrical properties.…”

Chemically deposited Sn-doped PbS thin films for infrared photodetector applications

Lead sulfide is a potential infrared (IR) photodetector material because of its favorable optoelectronic properties. The physical and chemical properties of PbS can be modified by a systematic doping of elements. In this study, we have doped 1-3 at% of Sn into PbS by a chemical bath deposition method. The undoped PbS films exhibited cubic crystal structure with a lattice parameter of a = 0.594 nm , an uneven grain growth, a direct optical band gap of 0.44 eV and a hole mobility of 8.9 cm 2 V −1 s −1 . The Sn-doping has improved the microstructure and slightly decreased the band gap of PbS. The hole mobility of PbS films has increased to 20 cm 2 V −1 s −1 with Sn-doping (1-2 at%). Thus, the PbS films grown by Sn-doping with improved microstructure, decreased band gap, and increased electrical properties are beneficial for IR photodetector applications.
