Abstract
Film heterostructures made of polymethyl methacrylate and low-density polyethylene with incorporated micron-sized particles of a semiconductor (graphite-like carbon nitride g-C3N4), fabricated using a component mixing and casting technique, were studied. Such heterostructures are relevant for the creation of new environmentally friendly optical elements for information processing. Free-standing continuous films based on polymethyl methacrylate and low-density polyethylene with a thickness of 30–50 μm and porous films based on polymethyl methacrylate with a thickness of 50–500 μm were created. The content of the added semiconductor was 5 wt.%, which ensured their integrity and mechanical stability during transportation and subsequent studies. Based on the optical transmission spectra of these films and their photoluminescence, it was established that g-C3N4 incorporated into the studied polymer matrices retains its size and semiconductor properties. The particles are distributed quasi-uniformly in the synthesized materials. It was found that the transmission spectra of the studied heterostructures have a quasi-linear dependence of the intensity of transmitted radiation on the wavelength of the incident radiation, which can be used in photonics to create spectrally sensitive elements.
