Abstract

ZnO is identified as one of the promising coating materials in optical fiber for ammonia gas sensors. In this work, three-dimensional ZnO nanoflowers are fabricated via a facile hydrothermal method and used as sensitive coating materials for optical fiber ammonia gas sensors. Results show that the sensor with ZnO nanoflowers exhibits a high sensitivity of 5.75 pm/(μg·L) for ammonia concentration ranging from 0 to 5460 μg·L, which is more than 2.6 times higher than that of the sensor with a coating of ZnO microspheres [2.2 pm/(μg·L)].

摘要

氧化锌被认为是用于氨气传感器的光纤中一种很有前景的涂层材料。在这项工作中，通过一种简便的水热法制备了三维氧化锌纳米花，并将其用作光纤氨气传感器的敏感涂层材料。结果表明，具有氧化锌纳米花的传感器对浓度范围为0至5460μg·L的氨气表现出5.75 pm/(μg·L)的高灵敏度，这比具有氧化锌微球涂层的传感器[2.2 pm/(μg·L)]的灵敏度高出2.6倍以上。
