Novel Dy incorporated CaYBO phosphor: Insights into the structure, broadband emission, photoluminescence and cathodoluminescence characteristics.

This study reports cathodoluminescence (CL) and photoluminescence (PL) properties of undoped borate CaYBO and CaYBO:x Dy (x = 0.5, 1, 2, 3, 5, and 7) synthesized by gel combustion method. Micro-X-Ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), CL and PL under electron beam and 359 nm pulse laser excitation, respectively were used to investigate characterization and luminescence studies of synthesized samples in the visible wavelength.
