Advanced luminescence applications of 3d3 transition metal ions

Transition metal ions with a 3d³ electronic configuration are among the most prevalent dopants in luminescent materials, favored for their distinctive energy level configurations and the ability to tailor their spectroscopic properties by modulating the crystal field strength. Despite a history of applications spanning over six decades, recent years have seen a surge in increasingly sophisticated and innovative applications that warrant particular attention. Consequently, this paper will provide a comprehensive overview of the potential uses of phosphors ion-doped with a 3d³ electronic configuration in advanced applications including: laser, lighting, NIR vision, plant cultivation, temperature and pressure sensing, optical heating, fingerprint detection, optical power meters.
