摘要
明溪蓝宝石呈色是铁、钛、铬等杂质过渡金属离子电子跃迁和电荷转移等因素共同作用的结果 ,但蓝色的深浅与铁的含量不呈简单的正相关关系 ,而更多地与铁、钛间含量的配比相关 ;Al2 O3 中 OH的振动应成为人们关注的蓝宝石呈色影响因素之一。
The coloration of sapphire from Mingxi is caused as a result of electron transition and charge transfer of transitional metal ions(e.g.iron,titanium,chromium, etc.). The sapphire color doesn't depend simply on the content of iron, but relates even more to the ratio of iron and titanium. The vibration of OH in Al 2O 3 ought to be the color causing factors of sapphire.
