| Popis: | Photoluminescence (PL) emission properties of hydrothermally synthesized zinc sulfide (ZnS) and doped (Cu2+, Eu3+, Cu2+ and Eu3+) zinc sulfide microspheres were studied. The samples were characterized by X‐ray diffraction, energy‐dispersive X‐ray analysis, field emission scanning electron microscopy, ultraviolet–visible and photoluminescence spectrophotometers. Hydrothermally synthesized ZnS microspheres give a broad emission in the 405–750 nm range. The quenching of broad PL intensity was observed in the Cu2+ ions and Eu3+ ions separately doped ZnS samples. ZnS microspheres codoped with Eu3+ and Cu2+ ions gives narrow and enhanced yellow–orange emission (530–650 nm) that desired for the bioimaging applications and fabrication of white light-emitting sources. |
