摘要：

We investigated the synthesis and writing-erasing properties of three different hybrid materials (SGDR1, SGDR13 and SGDR19) based on disperse red by the soL-gel process. The sol-gel process was undergone using tetraethyl orthosilicate (TEOS) as a precursor. Optical properties of three hybrid materials are compared as structurally similar materials (SGDR1, SGDR13 and SGDR19). The diffraction efficiency, reversible photoinduced process and writing-erasing properties of hybrid materials were measured as a function of time. The diffraction efficiencies of SGDR1, SGDR 13, and SGDR 19 films were observed up to a level of 0,65%, 0.24%, and 0.99%, respectively. AFM view of the surface relief grating on the SGDR19 film showed a depth of 15 nm and a surface distance of 2.50 mu m. (c) 2005 Elsevier Ltd. All rights reserved.
