摘要：

Optical measurements have been made on glasses quenched from a series of sodium silicate melts as well as germanate, borate, and phosphate liquids containing CoO. The spectral data show that Co+2 is the species stabilized in oxide melts heated in air. The observed bands occur at 2700-3850, 5750-7900, and 15 500-18 600 cm(-1). The independence of the optical parameters from melt composition and known melt structures, the high relative intensity of the high-frequency band, and the low calculated value of the Racah B parameter relative to the free ion value indicate that Co+2 forms a distinct tetrahedral complex in the quenched melt.
