概要

• 論文の詳細を見る

• Ni2+ ions occupy the tetrahedral (4), trigonal bipyramid (5) and octahedral (6) sites in glasses and glass-ceramics. The color changes depending on coordination number, typically pink for tetrahedral site, brown for trigonal bipyramid and tetrahedral sites and green to blue for octahedral site, respectively. The broad near infrared (NIR) emission peaking at around 1220 nm was observed for octahedral Ni2+ ions. This emission is due to 3T2(F)→3A2(F) transition.
