Summary
Heated objects such as sun, filaments of incandescent bulbs, etc emit light. It is known as thermal emission (black body emission). Since broad-band light emission can be obtained by simply heating objects, thermal emission sources are widely used for illumination, gas sensing and thermo-photovoltaic power generations. However, in each application very narrow-band emission is used among the broad-band emission. Hence, in general, utilization efficiency of thermal emission sources remain very low. In this seminar, control of thermal emission to obtain emission only at design wavelength by manipulating electronic and photonic states will be discussed. Furthermore, applications based on controlled emission sources will be explained.
