摘要：

As an example for a photochromic system we study an active fulgide in a polymer matrix. For theoretical description a two-state model is suggested. Absorption spectroscopy, m-line spectroscopy and UV real-time holography are tools to characterize the optical properties of the guest/host system. The photoinduced refractive-index change is about 7.5 x 10(-4) per % dye concentration. The diffraction efficiency of the holographic grating induced by W-illumination reaches a high value for photochromic materials of about 7%. The obtained gratings are nonlinear in the case of higher exposure energies.
