Excitability cultivation in high-energy UV region for Dy3+ in phosphate glass phosphors

Effective excitation region of Dy 3+ has been expanded from low-energy ultraviolet (UVA) to high-energy ultraviolet (UVC) by the introduction of sensitizers into Dy 3+ doped phosphate (NMBAP) glass phosphors. The cooperative effect of the sensitizers Ce 3+ and Sb 3+ generate remarkable enhancement on the fluorescence emission of Dy 3+ , attributing to the broadening of energy transmission channel to Dy 3+ . Diversified sensitization gain effects from tri-doped glass phosphors are discovered, providing a novel choice for the fluorescent optimization of Dy 3+ . Spectrum and image tracking confirm the Ce 3+ and Sb 3+ included Dy 3+ doped NMBAP glass phosphors possess outstanding excitation response in whole UV region, which compensates the deficiencies in Dy 3+ single-doped case. Intense fluorescence sensitization and delightful excitation extending in high-inclusive phosphate glass phosphors provide feasible routes for developing optoelectronic devices of light conversion, radiation detecting and laser illumination.
