Abstract

Cathodoluminescence (CL) emission and photoluminescence (PL) emission and excitation spectra of 16Na₂O–9NaF–5LaF₃–7Al₂O₃–63SiO₂ (mol%) activated with 3% PrF₃, hereinafter referred to as NaLaF₄:Pr³⁺, have been investigated. In particular, CL spectra were measured with time resolution after excitation with a 120 keV electron beam. The characteristic Pr³⁺ ion emission with fast decay times τ1=1.77 ns and τ2=52.97 ns at peak intensity at 406 nm were observed, which correspond well to the emission bands of the Pr³⁺ ion in other luminescent materials.
