Red-yellow CdSSe-ZnS SLs and blue-green SrS and CdSSe-SrS SLs double insulating EL devices prepared by hot wall epitaxy

Simplistic construction of cadmium sulfoselenide thin films via a hybrid chemical process for enhanced photoelectrochemical performance

“…22 The incorporation of selenium in cadmium sulde thin lms lowers the band gap energy and enhances absorption and spectral sensitivity, which are benecial for light harvesting in the visible region of the solar spectrum. 23,24 Cd(S 1Àx Se x ) ternary thin lms have been prepared by using various techniques, such as chemical bath deposition (CBD), 25,26 the metal catalyzed vapor liquid method, 27 screen printing followed by sintering, 28 hot wall epitaxy, 29 pulse printing, 30 a solvothermal route 31 and sputtering. 32 Conversely, these methods require harsh experimental conditions, a toxic reducing agent, organic surface directing agents, solvents and highly sophisticated instruments.…”
