- Аннотация: This article presents a new simple method of creating light absorbing carbon material for optical devices such as bolometers. A simple method of laser microstructuring of graphene oxide is used in order to create such material. The absorption values of more than 98% in the visible and more than 90% in the IR range are achieved. Moreover thermal properties of the films, such as temperature dependence and the thermal response of the samples are studied. The change in resistance with temperature is 13 Ohm K-1, temperature coefficient of resistance (TCR) 0.3 % K-1 and the sensitivity of 0.17 V·W-1 at 300 K. Thermal conductivity is rather high ~104 W m-1 K-1 at 300 K. Designed bolometer operates at room temperature using incandescent lamp as a light source. This technique suggests a new inexpensive way to create a selective absorption coating and/or active layer for optical devices. Developed GO and rGO films have a large surface area and high conductivity. These properties make carbon coatings a perfect candidate for creating a new type of optoelectronic devices (gas sensors, detectors of biological objects and etc).
