Description
Summary:•A foundation for developing light-powered MEMS is presented.•Near IR absorbant gold nanoparticles are characterized on a surface.•Temperature change due to applied 808nm light is shown for bare and near IR absorbant nanoparticle-coated surfaces.•Thermal efficiency is calculated for fabricated thin-film devices.•Surface response to changing near IR laser intensity is presented. This report presents characterization of the optical absorption and thermal properties of a thin-film platinum device coated with gold nanoparticles. These particles are engineered to have a light absorption peak near 808nm. The response of bare and particle-coated thin-film platinum was examined under an 808nm infrared laser. The results show that a particle coating is a significant factor in the thermal efficiency. This work is the foundation for wavelength-specific microelectromechanical actuators powered by infrared light.
