Luminescence of Cr3+ ions in Na2MgAlF7
The luminescence properties of Cr3+ ions in powdered Na2MgAlF7 multicrystal were studied experimentally. The fluorescent emission from 4T2 covers a wide region of 700 nm-1050 nm in the near-infrared. At 77 K, the fluorescence lifetime is about 310μs and the decay curve deviates slightly from single expenential form Temperature quenching occurs at above 200K. Several structures on the spectra are discussed.
