Crystallographically altered (Mg,Sr) 3 (Al,Ga) 2 GeO 8 :Cr 3+ phosphors with tuned emission width from the ultra-sharp red to profound NIR band

Puntos clave

• The aim is to transform sharp deep-red emission from Cr3+ into a broader near-IR range in phosphors.
• Conceptual design of phosphors with modified crystal structures
• Synthesis and characterization of (Mg,Sr)3(Al,Ga)2GeO8:Cr3+
• Analysis of emission properties and wavelength tuning
• Successfully converted deep-red Cr3+ emission into intense broadband near-IR emission
• Achieved tunable peak and width in a single phosphor
• Demonstrated significant potential for smart lighting and imaging applications
