2018年10月6日 · We report the synthesis of magnetite (Fe 3 O 4) and polyvinylpyrrolidone (PVP) coated Fe 3 O 4 nanoparticles by chemical co-precipitation route. X-ray diffraction (XRD) and transmission electron microscope (TEM) confirm the formation of inverse spinel structure of Fe 3 …

2020年6月8日 · pvp的红外光谱可以通过两种方法测得，一是采用kbr压片，二是将pvp水溶液洒在agcl圆盘上形成pvp的薄膜，然后测定。 各种方法得到的PVP红外光谱大同小异，只是当PVP含杂质太多或有可以与PVP分子发生相互作用的分子时，PVP的红外光谱可能会出现较大的偏差。

文献没注意，我是以前用pvp合成材料的时候，做过x射线衍射，结果能够看到衍射峰。 我昨天查到了几篇文献，里面提到了PVP的XRD，在25°附近就个较大的衍射峰，不知道您做出来的是否也是这样的结果

使用Positronics 研究了在聚乙烯吡咯烷酮 (PVP) 水溶液中进行湿纳米研磨的玻璃状砷化物 g-As x Se 100-x (5 ≤ x ≤ 65) 中的纳米结构化效应，Positronics是一种先进的表征工具，可追踪固体中的自由体积实体基于正电子湮没寿命（PAL）光谱。
