Weyl ( 1951 ) attributed the blue color to a CoO4 complex and the pink color to a
CoOo complex , but noted that the ... Similar conclusions were reached in a
comprehensive study by Aglan and Moore ( 1955 ) on the colors of cobalt in
glass .

CeO2 can also be introduced into glasses to control the valence equilibrium of
other impurities or dopants and thereby control the color of the glass ( Weyl ,
1951 ) . In some host glasses such as the lead silicates , the tail of the Ce4 + ...

Although the darkening is approximately two orders of magnitude lower than the
limit one would expect if each incident photon gives rise to one color center
having an oscillator strength of one , it is probably adequate for many
applications .
