摘要	The observation of photon-gated hologram formation in a boric acid glass doped with triphenylene is reported. The first photon excites triphenylene to its first singlet excited state and, through intersystem-crossing, populates the first triplet state T1. The second photon excites T1 to T(n) where autoionization occurs, leading to the formation of a radical cation. The gating light populating T, via S1 is spatially uniform, while the light exciting T1 to T(n) is spatially modulated. The long lifetime of the first triplet state allows recording with low light intensities (mW/cm2). The spatially modulated excitation light form three gratings (educt, intermediate state, and product). The extent of the interaction between these gratings depends on the overlap between educt, intermediate, and product absorption and refraction spectra as well as on the reading wavelength. The holograms were read at 363.8 and 632.8 nm. When the gating light is blocked, the holographic efficiency stays constant when read at 632.8 nm but increases substantially when read at 363.8 nm.
