Y. Hosoya et al., 2ND-HARMONIC GENERATION OF N-(4-NITROPHENYL)-L-PROLINOL-DOPED ALUMINAFILM PREPARED BY A SOL-GEL PROCESS, Thin solid films, 256(1-2), 1995, pp. 4-7
A second harmonic generation (SHG) active non-linear optical alumina f
ilm has been prepared by aligning the non-linear optical dopant, N-(4-
nitrophenyl)-L-prolinol, in the alumina matrix by a sol-gel process. T
he enhancement of SHG may be described by the formation of a pseudo-bo
ehmite film in which the plate-shaped alumina sol particles are stacke
d in a card-pack structure.
