We have investigated the thermal radiation in the infrared regime from resistively heated microfabricated platinum (Pt) wires (heaters), patterned with gold nanoparticles (NPs). The purpose of this work is to enhance the emissivity of the Pt heaters by modifying their surface properties. Gold particles with diameters of 50nm and 100nm, respectively, were deposited on the surface of the heaters. Polarization resolved thermal radiation was measured at different temperatures. Measurements show that the intensity of the thermal radiation increases by a factor of 2-3 for heaters with NPs deposited compared with heaters without NPs deposited.
