Highly efficient and stable NIR phosphor for night vision and bio-imaging.

A recent study published in the KeAi journal Advanced Powder Materials explores the development of a highly efficient and stable near-infrared (NIR) phosphor for night vision and bio-imaging. The researchers, led by Gemei Cai at the Central South University in China, examined the luminescent properties and crystal field environment of Cr3+ in a special matrix. The study demonstrates the potential applications of these NIR light sources in night vision, bio-imaging, and non-intrusive detection. The findings present a Cr3+-activated NIR phosphor with outstanding luminescence for multi-functional applications. [Extracted from the article]
