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.

Summary
The novel nanomaterials have attracted tremendous of attention over the past years due to those fascinating properties. Based on the light-to-heat study of the noble metal, carbon materials and chalcogenide semiconductor, perhaps the light-induced heat film heater is an interesting element in the heating filed.[24,25,26] Layered bismuth selenide (Bi2Se3), an important topological insulator, is a promising material in the application of high-performance infrared detectors, thermoelectric device[27,28,29] owing to its remarkable infrared transmittance, electrical and thermal properties.[30,31,32]. The photothermal temperature of as-fabricated Bi2Se3 film can be precisely tune by changing the incident laser power These excellent results indicate that Bi2Se3-based optical-thermal heating film will hold great promise for no-contact temperature control heater
