The Impact of MEH-PPV Organic Thin Film on the Emission andthe Q-Factor of L3 Nanocavities

الملخص

     In this paper, the influence of removing three holes called L3 nanocavities to achieve a high quality factor (Q-factor) of two-dimensional photonic crystal (2D-PC) and its optical properties were investigated. There are two important factors that are modified to obtain a high quality factor, which are changing the hole size, and after that, hole shifting. Next, the effect of organic-semiconductor materials on the cavity photoluminescence (PL) photonic crystal (PC) was studied. Fabrication techniques to create the photonic crystal L3 nano-cavity are described. In addition, the impact of the deposited organic-semiconductor emitter spectrum on the electromagnetic field intensity within the L3 nanocavity was measured using photoluminescence spectroscopy. Finally, the hole size of the (2D-PC) nanocavities and its lattice constant were characterized utilizing scanning electron microscope (SEM).
