硫化铋微米花的制备及其光响应性能
Synthesis and High Photoresponse Property of Bi2S3 Microflowers
摘要
Abstract
Bi2S3 microflowers with diameter of 4μm composing of nanorods were successfully synthe-sized via a mixed solvent hydrothermal method,and the influences of different reaction time and sol-vent ratio on the morphology were also studied.Then the Bi2S3 microflowers were deposited on pat-terned ITO glass substrates by dip-coating to fabricate photodetectors.The photoresponse properties using Bi2S3 microflowers as a representative system show that the photocurrent under simulated sun-light is 50 times larger than that of the dark current,the response and decay time are estimated to be 227ms and 880ms,respectively,indicating the photodetector has excellent photoelectric responsive-ness;the light current is not obviously attenuated by the periodic opening and closing of the photode-tector,indicating that the photodetector has good stability.关键词
