Effect of heavy-do** Eu3+ and charge compensation on crystalline phase and luminescence properties of K2CaP2O7 phosphors emitting orange-red light
A series of K2Ca1-xP2O7:xEu3+ phosphors were prepared by a high-temperature solid-state reaction method. The crystal structure was analyzed by X-ray diffraction (XRD). Fluorescence spectra, decay curves, and colo...
