To study the binding possibilities of Zn²⁺, Ca²⁺ and Cu²⁺ ions in the glassy phosphate network, metaphosphate glasses of xZnO-(50-x)CuO-50P₂O₅ and yCaO-(50-y)CuO-50P₂O₅ systems were prepared across the entire composition lines. Using Raman spectroscopy, ³¹P MAS NMR, electron paramagnetic resonance (EPR) and differential scanning calorimetry (DSC), it was found that zinc and copper are both four times coordinated and interact with donor oxygens in the same phosphate chain, calcium is six times coordinated and crosslinks phosphate chains significantly increased by this the glass transition temperature. It was further found that all copper-containing glasses are phase separated, which is also clearly reflected, in addition to the ³¹P MAS NMR and EPR spectra, in the compositional dependence of the glass transition temperature. The experimental results obtained by all the techniques used are discussed in detail.

为了研究Zn 2 ⁺，Ca ²⁺和Cu ²⁺离子在玻璃态磷酸盐网络中的结合可能性，xZnO-（50-x）CuO-50P ₂ O ₅和yCaO-（50-y）CuO-的偏磷酸盐玻璃在整个合成生产线上准备了50P ₂ O ₅系统。使用拉曼光谱，³¹P MAS NMR，电子顺磁共振（EPR）和差示扫描量热法（DSC），发现锌和铜都是四倍配位并与同一磷酸链中的供体氧相互作用，钙是六倍配位并且使磷酸链交联由此玻璃化转变温度显着提高。进一步发现，所有含铜玻璃都是相分离的，除了³¹ P MAS NMR和EPR光谱外，在玻璃化转变温度的成分依赖性上也能清楚地反映出来。将详细讨论通过所有使用的技术获得的实验结果。
