Additionally, the humidity sensitive indicator was embedded on the surface of the fiber core fabricating a long-range fiber optic humidity sensor. The composition of the sensitive films were analyzed by energy dispersive X-ray detector(EDX).

• 通过X射线能谱仪(EDX)对所制备的pH和湿度敏感膜的表面成分进行了分析,并采用光功率计对敏感膜进行了光学检测。
