Ferric iron‐substituted sodium metaphosphate and calcium metaphosphate glasses exhibit a very weak luminescence that can be observed under laser excitation. Broad emission bands at 16 000 cm −1 and at 12 000 cm −1 are assigned to the 4 T 1 → 6 A, transitions of Fe 3plus; in four‐ and six‐coordinated sites respectively. The interpretation is supported by crystal field theory calculations based on known absorption spectra of Fe 3plus; .
