Advances in Chromium‐Activated Phosphors for Near‐Infrared Light Sources
University of Science and Technology Beijing
Abstract
Abstract Cr 3+ /Cr 4+ ‐activated near‐infrared (NIR) luminescent materials have attracted extensive attention owing to their tunable emission wavelength and widespread applications in plant growth, food analysis, biomedical imaging, night vision, and so on. Plenty of excellent NIR materials are developed by introducing Cr 3+ /Cr 4+ ion to various inorganic hosts. Herein, the effect of crystal field on Cr 3+ /Cr 4+ luminescence by combining the Tanabe–Sugano energy level diagram and configuration coordinate model is discussed. Research progress of Cr 3+ /Cr 4+ ‐doped NIR luminescent materials, including the phosphors designed from structural models with octahedral, tetrahedral, and other coordination types, is…
