Luminescence of Solutions of Terbium Salts

Naturevolume 139pages248249 (1937) | Download Citation



VERY dilute aqueous solutions of terbium salts exhibit a bright luminescence when excited by the ultra-violet rays1. The maximal excitation is caused by the absorption of the wave-lengths coinciding with the broad absorption band of terbium, stretching from 290 m far towards the short wave-lengths2. The spectrum of this luminescence consists of 7 bands, each band being nearly 100 A. wide. The wavelengths and frequencies of the middles of the bands are given in the accompanying table.
