The blue-green emission color of Ag+, Gd3+ co-activated CdWO4 phosphor via energy transfer for luminescence applications

Ag+, Gd+3-doped CdWO4 (co-doped CWO) phosphor nanopowders were synthesized by an eco-friendly method and then embedded into the polymer matrix to produce a flexible and transparent thin film. A novel phosphor for the excitation by an ultraviolet source, 980 nm diode laser, and proton radiation was r...

Description
Summary:Ag+, Gd+3-doped CdWO4 (co-doped CWO) phosphor nanopowders were synthesized by an eco-friendly method and then embedded into the polymer matrix to produce a flexible and transparent thin film. A novel phosphor for the excitation by an ultraviolet source, 980 nm diode laser, and proton radiation was reported at room temperature and crystal structure, luminescent properties, and energy transfer between Ag+ and Gd+3 ions were thoroughly investigated. Elemental composition and chemical state analyses were measured using X-ray photoelectron spectroscopy and energy dispersive X-ray spectroscopy studies. Crystal structure and phase identification were confirmed using powder X-ray diffraction measurement. Based on all results, the flexible phosphor film prepared has good thermal stability and efficient blue-green emission under UV light, laser, and proton excitation used in emissive displays applications. [Display omitted] •Ag+, Gd3-codoped CdWO4 phosphors were synthesized successfully.•A transparent flexible luminescent composite based on co-doped CWO phosphors was obtained.•The prepared composite exhibited brilliant narrow-band visible tunable emission.
