Abstract

Malachite green introduced into glasses exhibits a characteristic spectral behaviour depending on the mode of preparation of the glass and its environment. Neutral, mono-cation and di-cation forms can be prepared. Exceptionally high quantum efficiency is obtained with ammonia treatment. An analogy is found in the structure with electron or proton transfer.
