Ag and Dy doped zeolite as a broadband phosphor
Source abstract
Abstract
Abstract Photoluminescence (PL) properties of silver (Ag) and dysprosium (Dy) codoped zeolites were investigated. It was found that PL from the 4F9/2–6H13/2 transition of Dy3+ ions at 575 nm is more than 50 times enhanced by the presence of Ag+ ions under ultraviolet excitation. The excitation wavelength dependence of the PL intensity coincided well with the absorption spectra of Ag+ ions, indicating that Dy3+ ions are excited by the energy transfer from Ag+ ions. In addition, by carefully optimizing annealing condition and Dy and Ag concentration, white light was realized due to the combination of blue emission of Ag+ ions, yellow emission of Dy3+ ions and red emission of Ag clusters.
