摘要
本文对稀土元素在宝石玻璃中着色效应进行了详细研究,定型了多色宝石玻璃工艺,研究结果表明:基态光谱项为I,H的稀土元素具有多色性;基谱项为F高支谱项稀土元素有荧光效应;恰当配伍双稀土着色剂可拓宽色域。
In this paper, the colouring effect of rare earth elements in gem-glass has been studied in detail. The technigue of polychrome - gem - gle ass has been fixed andat the some time, It is proved that the rare ear nth elements possessing 'I' 'H' base terms of spectrum have a polych roism. The rare earth element whose base terms of spectrum is 'F' high-branch terms spectrum has fluorescence effect. properly mixing double rare eartb colourant can widen colourfiled.
