Optical and luminescent properties of Dy3+/Sm3+ doped and codoped Zinc Borophosphate glasses for W-LED application

In this work, a series of zinc borophosphate glasses (ZnPBAl), doped and codoped with Dy3+ and Sm3+, was studied for potential application in W-LEDs. The samples were prepared by the melt-quenching method and their luminescent and optical properties were investigated. The optical absorption spectra...

The 350 nm excitation source was chosen, considering photoluminescence excitation (PLE) results, to investigate the energy transfer from Dy3+ to Sm3+ ions.
