High efficient photothermal energy conversion of topologic insulator Bi2Se3 nanosheets thin film
Source abstract
Abstract
The photothermal conversion has become rather attractive to realize the heat energy application. A simple, rapid and scalable optical-controlling Bi2Se3 nanosheets film heater is prepared by softly nondestructive rubbing technology and then transferring to PET substrate under the assistance of PVA. The optical-controlling film heater exhibits the excellent adjustability, accuracy and stability of temperature. The film heater is first tested by using laser irradiation at 410 mW and the corresponding temperature rapidly increased to the 53.2 °C for SThin film and 73.2 °C for SThick film during 50 seconds. The SThin and SThick film display a transmittance of 40% to 60% from the visible to near-IR region, respectively. As-prepared optical-controlling Bi2Se3 film heater can be easily integrated to optical or photo-electric device without preparation of electrode. These exotic properties of Bi2Se3 nanosheets optical-controlling heater suggest exciting prospects for the temperature-dependent flexible optoelectronics and electronic device.
