摘要
鉴于紫色翡翠呈色机制复杂 ,至今在矿物学界、珠宝学界尚无统一认识 ,通过使用三件紫色系列翡翠样品作电子探针、透射光谱及吸收光谱分析 ,并进行了相关讨论。认为 :不同紫色翡翠因所含有的过渡金属离子种类、含量不同 ,致使起主导作用的致色离子表现出不同的呈色机制 ;Ti3+中的 d- d电子跃迁是紫色翡翠呈色的主要原因。
There has been no consistent understanding of the coloration mechanism of purple jadeite in mineral and jewelry circle till now due to its complexity.It is concluded that different purple jadeites possess different coloration mechanism due to different kinds and amounts of metallic transition ions of the jadeite, which act as main coloration ions. d-d electron transition in Ti 3+ is considered to be the main cause of purple jadite coloration.
