摘要

采用铸造法制备了不同含量硝酸钛纳米颗粒(TiN NPs)的聚乙烯醇(PVA)/聚乙二醇(PEG)纳米复合材料。采用分光光度法对该纳米复合材料进行了分析，光谱范围为200 ~ 800 nm。当在聚合物基体中加入TiN纳米粒子时，吸收增强，可用于光电探测器等各种应用。随着TiN NPs含量的增加，间接跃迁(允许和禁止)的光能间隙减小。此外，还确定了所有光学常数。

Effect of Titanium Nitrate Nanoparticles on Optical Properties of PVA/PEG Blend for Optoelectronics Detectors

In this work, casting method was used to fabricate the polyvinyl alcohol (PVA)/ poly ethylene glycol (PEG) nanocomposite with different content of titanium nitrate nanoparticle (TiN NPs). This nanocomposite was analyzed to use a Spectrophotometry with a spectral region of 200-800 nm. The absorption enhances when the added TiN NPs to the polymeric matrix which may be used for various applications such as optoelectronic detector. The optical energy gap for indirect transition (allowed and forbidden) decreased as TiN NPs content increases. Moreover, all optical constants have been determined.
