众所周知，影响光电子器件工作的一个因素是有效保护半导体材料免受环境条件的影响。大气中的氧和水分子渗透到器件结构中引起电极和半导体的劣化。因此，在本通讯中，我们报告的制造的半导体膜组成的镁酞菁-丙二烯（MgPc-丙二烯）颗粒分散在尼龙11膜。这些膜将聚合物性质与有机半导体性质结合联合收割机，并且还为大气气体分子提供屏障效应。它们是通过高真空蒸发和随后的热弛豫技术制备的。对于所获得的膜的表征，傅里叶变换红外光谱（FT-IR），扫描电子显微镜（SEM），和能量色散光谱（EDS）被用来确定的化学和微观结构特性。利用紫外可见光谱、零椭圆偏振光谱和室温下的可见光致发光（PL）对薄膜的光电性能进行了表征。这些结果进行了比较与有机半导体：MgPc-联烯薄膜。此外，半导体膜器件已被制备，并通过测量电流密度-电压（J-V）特性的设备的电子输运特性的研究进行了由四个点探针具有不同的波长。增强了对不同环境分子的电阻特性，保持了它们的半导体功能，使它们成为光电应用的候选者。
It is known that one factor that affects the operation of optoelectronic devices is the effective protection of the semiconductor materials against environmental conditions. The permeation of atmospheric oxygen and water molecules into the device structure induces degradation of the electrodes and the semiconductor. As a result, in this communication we report the fabrication of semiconductor membranes consisting of Magnesium Phthalocyanine-allene (MgPc-allene) particles dispersed in Nylon 11 films. These membranes combine polymer properties with organic semiconductors properties and also provide a barrier effect for the atmospheric gas molecules. They were prepared by high vacuum evaporation and followed by thermal relaxation technique. For the characterization of the obtained membranes, Fourier-transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and energy dispersive spectroscopy (EDS) were used to determine the chemical and microstructural properties. UV-ViS, null ellipsometry, and visible photoluminescence (PL) at room temperature were used to characterize the optoelectronic properties. These results were compared with those obtained for the organic semiconductors: MgPc-allene thin films. Additionally, semiconductor membranes devices have been prepared, and a study of the device electronic transport properties was conducted by measuring electrical current density-voltage (J-V) characteristics by four point probes with different wavelengths. The resistance properties against different environmental molecules are enhanced, maintaining their semiconductor functionality that makes them candidates for optoelectronic applications.
