Erbium doped Barium Tungstate-Chitosan Nanocomposite: Luminescent Properties
Recently, there has been an increase in the ability to adjust the optical band gap and enhance the brightness of luminescence in nanophosphors that are used in light-emitting diodes and detectors. In this study, a flexible nanocomposite of erbium-doped barium tungstate (BaWO4:Er-1at.%) thin film was...

| description | Recently, there has been an increase in the ability to adjust the optical band gap and enhance the brightness of luminescence in nanophosphors that are used in light-emitting diodes and detectors. In this study, a flexible nanocomposite of erbium-doped barium tungstate (BaWO4:Er-1at.%) thin film was synthesized via co-precipitation method, and the structural and luminescence properties were investigated. The effect of excitation wavelength ( ) was studied on the optical properties of the synthesized composite at room temperature. Doped nanocomposite showed the best visible emission in the blue-green range at excitation wavelength =250) of a xenon lamp and a strong violet emission under 980 nm laser excitation. The XRD results verified the presence of BWO, in the chitosan composite structure. FESEM images showed that the prepared hybrid nanocomposite's surface was smooth, consistent, and compact; The Er:BWO particles exhibited a flower-like morphology. These findings demonstrate the potential for employing this nanocomposite in the fabrication of high-performance optoelectronic devices. |
