Photosensible nanocomposites pepc/ana-ch: preparation technique and some optical properties

Nanocomposites based on polymers and organic luminophore materials (propenone and coordinated with rare earth elements) are excellent structures for a new generation of devices with high intensity of luminescence in the visible region of the spectrum [1, 2]. The main advantages of nanocomposites are...

description	Nanocomposites based on polymers and organic luminophore materials (propenone and coordinated with rare earth elements) are excellent structures for a new generation of devices with high intensity of luminescence in the visible region of the spectrum [1, 2]. The main advantages of nanocomposites are their high stability due to fixation and protection in the polymer matrix; they can be obtained in the form of thin layers on large-area and flexible substrates and in the form of fibers and planar waveguides; they are promising for broad application in optoelectronics and other fields, such as solar cells, gas sensors, medicine, etc. The samples of 3-(anthracene-9-yl)-1-(4-isothiocyanatophenyl)-prop-2-en-1-one (ANA-CH) framed in the polymer matrix of polyepoxypropylcarbazole (PEPC) were prepared and characterized by optical spectroscopic methods. For the ANA-CH and ANA-CH/PEPC nanocomposites, depending on the composition, the photoluminescence peaks at photon energy hv=3.16 eV, hv=2.45 eV and hv=3.18 eV, hv=2.25 eV, respectively, were registered. The peaks in the photoluminescence spectra of the investigated nanocomposites can be attributed to the presence of the CH=CH double bond in the organic luminophore compound with the width of λ=117 nm at room temperature and λ =37 nm at nitrogen temperature.
