| Abstract: | In this work, CaS phosphors were synthesized using the sol–gel method with doping of rare earth metals such as Eu, Dy, and Tm in combination. The optimization of the dopant concentration at 2% allowed for the adjustment of the samples' characteristics. Detailed analyses were carried out, including X-ray diffraction studies, evaluation of photoluminescence characteristics, examination of hemocompatibility, and determination of the average lifetime of the excited state for this novel set of CaS phosphors. The synthesized phosphors displayed intense greenish-yellow emissions at a wavelength of 543 nm, which can be attributed to the electric dipole transition resulting from the dopants. Among the different compositions, the CaS phosphors doped with 2% Eu and 2% Dy showed exceptional structural and morphological qualities. Additionally, this composition exhibited the highest hemolysis inhibition percentage, with 82.37% of red blood cells remaining viable. Moreover, this particular sample demonstrated the maximum light efficacy in terms of radiation and excitation purity. The study emphasizes the luminescent properties and biocompatibility of the CaS phosphor, particularly when enhanced through doping. The findings suggest promising potential for the application of these phosphors in the field of bioimaging. [ABSTRACT FROM AUTHOR] |
