In the present work, Cr doped tellurium dioxide nanostructures (CTO NS)(1 wt %, 6 wt %, 8 wt % and 12 wt %) synthesized by co precipitation method and characterized by CV, UV‐Visible, SEM, XRD, XPS spectroscopic analysis. Electron beam deposited thin film of CTO NS having 12 wt % of Cr exhibited EGFET‐pH sensitivity of 62.03 mV/pH at 250 °C in buffer solutions of pH 6–12, linearity 0.9345, drift rate of 1.12 mV/h and deviation of 0.01145 as compared with 1 wt %, 6 wt % and 8 wt % of CTO NS.

Cr掺杂TeO2纳米结构的合成,表征及其在EGFET pH传感器中的应用
在本工作中,通过共沉淀法合成了Cr掺杂的二氧化碲纳米结构(CTO NS)(1 wt%,6 wt%,8 wt%和12 wt%),并通过CV,UV-Visible,SEM,XRD,XPS进行了表征光谱分析。电子束沉积的具有12 wt%Cr的CTO NS薄膜在250°C的pH 6–12缓冲溶液中显示EGFET-pH灵敏度为62.03 mV / pH,线性度为0.9345,漂移率为1.12 mV / h,偏差为与1wt%,6wt%和8wt%的CTO NS相比为0.01145。
