Emission from nanocarbon as a point white-light source is studied in several scientific experiments, i.e., a demonstration of chromatic phenomena of a refractive lens, a diffractive Fresnel phase zone plate (FPZP), and a squared zone plate. Results show that white light from nanocarbon exhibits good coherent properties and can be an ideal point light source in comparison with other normal lighting sources, e.g., a light-emitting diode (LED), a He-Ne laser, and a semiconductor laser diode (LD). Dispersion and even diffraction phenomena could be analyzed this way as well.
