【摘要】 安绿玉属于利蛇纹石型的蛇纹石玉。通过穆斯堡尔效应研究,确认铁是参加组成晶格的组分,查明了铁离子的价态、占位及 Fe³⁺/Fe²⁺,接合配用的可见光吸收谱,证实铁是安绿玉的主要呈色离子,Fe³⁺/Fe²⁺同 Fe³⁺d—d 跃迁与 Fe²⁺→Fe³⁺荷跃迁的强度比直接相关,是安绿玉颜色的主要制约因素。更多还原

【Abstract】 Anl■-jade is a serpentine jade of the lizardite type.By the study of the M■ssbauer effect,the author has conformed that Fe is a component of the lattice,defined the valence state and site occupancy of Fe ion and the ratio of Fe³⁺/Fe²⁺,and in combin- ation with visible light absorption spectrum,he has further proved that Fe is the main colo- uring ion of Anl■-jade.Fe³⁺/Fe²⁺ is directly correlated to the ratio of the strength of jum- ps of Fe³⁺ d-d to that of charge jumps of Fe²⁺→Fo³⁺ and therefor Fe is the main controlling factors of the colour of Aul■-jade.更多还原
