摘要
Abstract
Barium fluoride (BaF2) crystals were colored by electric injection using a pointed anode with a homemade electric injection apparatus at various temperatures and voltages. The current versus time relationship during the electric injection was determined. The absorption spectra of electric injection colored BaF2 crystals at room temperature were analyzed. The results show that the massive F color centers are produced in the colored crystals. According to the electric injection coloration mechanism, the F color centers could not be produced by using a pointed anode. By using measured current-time curves, we could explain the mechanism ofF color center formation for the electric injection colored crystals. In the electric injection coloration process, V color centers inside the crystal were initially produced near the anode, and then the F color centers were transformed from the V color centers absorbed photons.关键词
