N21型磷酸盐激光玻璃中铂离子的吸收光谱及其与铂微粒的关系

Relationship between absorption spectrum of ionic platinum and density N of platinum particles in N21 phosphate laser glass

根据对磷酸盐激光玻璃中铂离子吸收光谱的研究,发现了铂离子吸收带的λ_(max),S/H与铂微粒夹杂物密度N之间的关系,应用不同价态铂离子间的氧化还原平衡方程,Pt^(4+)与Pt^(2+)与Pt^0对实验结果进行了解释,提出了消除铂微粒产生应遵循的原则。

From the absorption spectrum of Pt+4 and Pt+2 we found the correlation among λmax, S/H in Pt ionic absorption band and platinum inclusion density N. Relations between oxygen partial pressure and oxido-reduction balance in equilibrum equation Pt4+ Pt2+ Pt0 are also explained. The rules of removing platinum inclusion are presented.
