Luminescence Properties of an Orthorhombic KLaF<sub>4</sub> Phosphor Doped with Pr<sup>3+</sup> Ions under Vacuum Ultraviolet and Visible Excitation

Luminescence Properties of an Orthorhombic KLaF<sub>4</sub> Phosphor Doped with Pr<sup>3+</sup> Ions under Vacuum Ultraviolet and Visible Excitation

Fluorides have a wide bandgap and therefore, when doped with the appropriate ions, exhibit emissions in the ultraviolet C (UVC) region. Some of them can emit two photons in the visible region for one excitation photon, having a quantum efficiency greater than 100%. In a novel exploration, praseodymi...
