Organic electronics are expanding rapidly with more and more applications being discovered for it, and electroactive hydrocarbons are receiving attention among researchers, especially in the fundamental fields of science. Over the last two decades, the applications of organic technology have become unique and valuable in the electronic device industry. The main directions of development are observed in electronics, various sensors, bioelectronics, optoelectronics and various functional applications in solar cells. We witness different industries of organic and inorganic materials starting to complement each other. The use of inorganic materials in organic structures increases the efficiency of devices and creates a new generation of hybrid organic-inorganic structures. Organic layers are mainly produced by solution processing: drop-casting, spin-coating, “doctor blade” method and spraying purškiant. These methods make it possible to produce large-area and flexible devices. However, such methods require the mixing of polymers or small molecules with solvents, which complicates manufacturing processes and reduces the purity of layered structures. One of the alternative areas in which mixed organic and inorganic materials can be used is X-ray sensors. First, amine functional group polymers or molecules have been shown to be stable and applicable to direct X-ray detection. Particles of high atomic mass (large Z) elements increase the signal of these detectors. As a result, hybrid organic-inorganic methods are becoming unprecedented competitors for direct conversion (amorphous selenium or silicon) and indirect scintillator detectors (mostly CsI) used in industrial X-ray displays. In this work, the first X-ray sensitive layers by solvent-free methods (thermal melting) were produced. The layers were composed of small molecule and zinc cadmium sulfide using a two-glass tray structure. In addition, second series of layers was prepared from a mixture of three different molecules of carbazolyl branches and tungsten produced using the melt spinning method, which was tested and published for the first time (MSC - Melt Spin Coating). The structural and electrical properties of the layers are discussed, the charge generation of charge carriers is calculated by Monte Carlo modeling and the physical mechanism of sensor sensitivity increase is discussed, short-term and long-term transients and the perspective of such layers in industrial applications is evaluated. |
