We have made a diffraction grating in an indoline azobenzene/amorphous polycarbonate film by two-beam interference at 532 nm that periodically photodegrades the indoline azobenzene dye. Subsequent illumination of the film with 532-nm light into the t

Photostability measurements have been made on host-guest films containing amorphous polycarbonate and an organic chromophore with a high 2nd order nonlinear optical figure of merit. We find that the rate of photodegradation strongly depends on the ox

An optically switchable diffraction grating has been made in a thin film containing a photochromic dye and amorphous polycarbonate. We show that a film containing the dye 5-chloro-1,3-dihydro-1,3,3-trimethylspiro[2H-indole-2,3sup'/sup-(3H)naphth[2,1-

Publikováno v: Conference on Optoelectronic and Microelectronic Materials and Devices, 2004..

In this paper we report studies of the optical properties of silicon quantum dot structures. From time-resolved and time-integrated photoluminescence measurements we investigate the state-filling effect and carrier lifetime and discuss the parabolic
