Paper Abstract

Spectral management and diffusive light transport enables plants to both survive on extremely low irradiance and also to survive long enough under extreme temperature and pressure to leave imprints in super-heated impact glasses. These properties are related to structures wherein a low density of light absorbent particles are embedded in a light scattering and spectral selective reflective matrix. This marvelous diffusive light engineering has wide-ranging applications based on bio-mimicry. Where, environmentally sensitive radiative-to-non-radiative lifetime ratios increase the photon flux to the chlorophyll molecules best positioned for favorable photochemistry and for preservation under extreme conditions. The embedding of absorptive particles within a transparent scattering matrix has far reaching intriguing applications. Included is the extreme heating of light absorbent particles within a relatively cold matrix. Interestingly, the hot absorbent particle-cold matrix condition is critical for the efficient extreme heating of small particles. Here the potential of non-equilibrium passive diffusive light collection will consider be explored using one of the most challenging application extreme particle heating for controlled nuclear fusion.
