Light operated electrooptical materials based on the [(C2H5)3NH]2CuCl4/polymer nanocomposites

In this work, we proposed a new type of nanocomposite materials which possess a possibility to be operated with respect to the electrooptical coefficients at 633 nm wavelength. The material is a [(C2H5)3NH]2CuCl4/PMMA polymethylmethacrylate polymer nanocomposite. The operation is performed by external laser light at varied temperatures. The second harmonic generation of the Nd:YAG 532 nm pulsed laser with pulse duration 10 ns was used as a source of the photo-induced changes. At temperature about 320 K an enhancement of corresponding electrooptical response was observed. The effect was sensitive to the size of the corresponding nanocrystallites and the crystallite size was within the range 30–320 nm. The optimal content of the nanocrystallites is 12 % in weighting units.
