Abstract
A luminescence band at 770 nm due to iron centers has been observed in lithium niobate crystals treated at 520 °C in lithium carbonate. Without this treatment only a broad background luminescence was observed. The main effect of the treatment is to reduce iron centers to the Fe2+ state but some evidence was found that destruction of shallow traps is also involved in increasing the luminescence.Keywords
