Broadband near-infrared emission improvement of Cr3+ doped phosphors via co-doping Bi3+ ions

Key Points

• The broadband near-infrared emission of Cr3+ doped phosphors is significantly improved with Bi3+ co-doping.
• Measurements indicate an increase in emission intensity and broadened spectral range with Bi3+ addition.
• The approach involves co-doping which exploits interactions between Cr3+ and Bi3+ ions in the phosphor matrix.
• These findings highlight the potential for optimizing materials used in LED and laser applications.
