Thanks to the unique sharp red emission spectra and broadband excitation, Mn4+ions activated oxide host matrixes exhibit fascinating potential application in white light-emitting diodes (wLEDs). In this work, Mn4+activated LaGaO3with a perovskite structure were successfully synthesized via a solid state reaction, which exhibits a near infrared (NIR) emission with high brightness, locating around 710 nm. Moreover, the introduction of the transition metal Bi3+ions contributes to a remarkable improved luminescence output of Mn4+ions with enhanced internal quantum efficiency performance.
