Abstract

The unprecedented deep red-emitting phosphor, Ca19Ce-(PO 4)14:Mn2+, has been fabricated by a convenient solid-state method. A strong red emission centered at 637 nm corresponding to the 4T1(4G) → 6A1(6S) transition of Mn2+ is observed under 130-300nm excitation. The chromaticity coordinates of optimized phosphor were found to be (0.69, 0.29). In addition, we have also made an attempt to observe strong red emission displayed by this phosphor for use as coating material on compact fluorescent lamps (CFLs). It is a promising candidate for application in CFLs as a red-emitting color converter.
