Light operated electrooptical materials based on the [(C_2H_5)_3NH]_2CuCl_4/polymer nanocomposites

摘要

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 [(C_2H_5)_3NH]_2CuCl_4/ 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.
