摘要

Homogeneous monolith of A1PO4 gel doped with rhodamine 6G (Rh6G) at different dye loadings is prepared by a one-step process with sol-gel method using the precursors A1(lact)3 and H3PO4. The optical properties of A1PO4 gel doped with Rh6G are characterized by UV-Visible absorption spectra and fluorescence spectra. Rh6G molecular J-dimers and H-dimers even multimers are analyzed by excitation spectra based on exciton theory. The A1PO4 gel doped with Rh6G dye with molar ratio of Rh6G/A1(lact)3 of 1 * 10-4 has excellent optical properties without obvious aggregates.
