摘要
选取缅甸的白、淡粉紫和淡蓝紫3种颜色类型的翡翠样品,测试和分析了其元素和光吸收谱,并对其颜色成因进行了初步研究。结果表明,淡紫色翡翠样品含有少量的铁、锰和钛,而铬、钒、铜等元素的含量极低。除了Fe
3+的吸收峰之外,淡粉紫色翡翠光谱中还存在峰值位于566 nm处的宽吸收带,淡蓝紫色翡翠光谱中存在峰值位于534 nm处的宽吸收带及长波侧625 nm处的肩带,因此,淡粉紫色和淡蓝紫色翡翠分别由Mn
3+和Ti
3+离子致色。
Abstract
Three kinds of white, pale-pink purple and light-blue purple jadeite samples from Myanmar are selected for the test and analysis of elements and optical absorption spectra, and their color origins are preliminary studied. The results show that the lavender jadeite samples contain a small amount of iron, manganese and titanium, while the contents of chromium, vanadium and copper are extremely low. In addition to the absorption peak of Fe
3+, the pale-pink purple jadeite has a broad absorption band peaking at 566 nm, and the light-blue purple jadeite has a broad absorption band peaking at 534 nm and a shoulder band at 625 nm on the long-wave side. It is inferred that the pale-pink purple and light-blue purple jadeite are mainly colored by Mn
3+ and Ti
3+ ions, respectively.
