| Popis: | a b s t r a c t This report presents characterization of the optical absorption and thermal properties of a thin-film plat- inum device coated with gold nanoparticles. These particles are engineered to have a light absorption peak near 808 nm. The response of bare and particle-coated thin-film platinum was examined under an 808 nm infrared laser. The results show that a particle coating is a significant factor in the thermal effi- ciency. This work is the foundation for wavelength-specific microelectromechanical actuators powered by infrared light. |
