General description

Crystal structure of CaS is cubic. Electrical conductivity of calcium sufide in the temperature range of 650oC-1000oC was studied in great detail. It was concluded that CaS could be used as a potential electrolyte in a sulfur concentration cell.2

Application

Calcium sulfide may be used to remove heavy metals from wastewater.

Luminescence properties of individual BN-coated CaS:Eu nanowires have been studied by high-spatial-resolution cathodoluminescence (CL) spectroscopy. A broad red light-emitting band from an individual nanowire has been observed. Detailed local CL studies on the nanowires reveal spatial variations of luminescence from...

Spectral conversion for solar cells is an emerging concept in the field of photovoltaics, and it has the potential to increase significantly the efficiency of solar cells. Lanthanide ions are ideal candidates for spectral conversion, due to their high luminescence efficiencies and rich energy level structure that allows for great flexibility in the upconversion and downconversion of photons in a wide spectral region (NIR-VIS-UV).
