In the context of this research endeavor, the central objective revolved around the strategic design of CaS as a phosphor material with remarkable potential. This pursuit aimed to harness the inherent luminescent properties of CaS, rendering it a highly promising compound for diverse biomedical applications. A simple sol–gel technique was used to synthesize the calcium sulfide doped by dysprosium activator. Structural, morphological, luminescent, lifetime, and hemocompatibility were analyzed from various characterizations. Qualitative parameters, regarding the structure, morphology, and color of the light emitted, were enhanced due to doping. A Tauc plot was drawn using UV-absorption data, showing the results of the optical bandgap from 2.12 to 2.43 eV. The hemocompatibility test showed that the biocompatibility of the samples was enhanced due to doping. Enhanced luminescence in the visible region along with biocompatibility would make the sample suitable material for bioimaging applications.
