Zinc sulfide crystals are fired successively in a Zn liquid at 1184 °C and annealed isochronally. The emission spectra between 700 and 1200 nm and the optical absorption bands ascribed to F + centres are measured in the specimens. The Zn treatments introduce emission bands with peaks at 1.1 and 1.45 eV, which are reported by other workers. These bands are annealed in company with F + centers. Therefore it is proposed that these emission bands are due to F + centers.
