Achieving broadband NIR emission through multiple centers of isolated Cr 3+ and Cr 3+ –Cr 3+ ion pairs resulting from phase segregation in SrLa 2 Ga 2 O 7

Key Points

• The phosphor exhibits ultra-broad emission spanning 700–1200 nm, highlighting its potential for efficient light applications.
• The key emission results from Cr3+ ions and their pairs, formed through phase segregation in the lattice matrix.
• Synthesis was achieved using a solid-state reaction, ensuring the structural integrity of the active materials involved.
• Supports further exploration of Cr3+ ions in phosphors for advanced optoelectronic applications and device integration.
