Solution processable and photo-patternable titanium doped organic–inorganic hybrid material (MDT hybrimer) was prepared by simple sol–gel reaction for the gate dielectrics in organic thin film transistors (OTFTs). The MDT hybrimer is a typical nanocomposite which is fabricated via UV cross-linking of the nano-sized organo-oligosiloxanes. The photo-patternability of the MDT thin films was investigated using the UV light. The surface and electrical properties of MDT thin film were also investigated. The pentacene-based OTFT with MDT gate dielectrics was fabricated by using the top contact geometry. It is found that the OTFT with the MDT gate dielectrics showed a small hysteresis and good performance. The filed-effect mobility, threshold voltage, subthreshold slope and on/off current ratio of OTFT with MDT gate dielectric were 0.66 cm2V−1s−1, −14 V, 1.6 Vdec.−1, and 3 × 106, respectively.

Tungsten being a transition element, forms oxide compounds of various oxidation states that enables it to form nanocolloids of tungsten oxide dihydrate. Multiple methods have been used in recent years to synthesize nano tungsten oxide dihydrate, including sol-gel synthesis, electrochemical deposition, hydrothermal synthesis and anodization. However, a universally accepted synthesis method for this material is not offered. The most appropriate method and its corresponding processing parameters for the synthesis of nano tungsten oxide dihydrate colloids were presented in the present study. The objective of the present study was to investigate the effect of processing parameters, i.e. applied voltage, temperature and anodizing duration on the particle size of nanocolloids. It is found that anodization is the easiest, efficient, and cost-effective method to synthesize the colloidal solution of nano tungsten oxide dihydrate. Conducting the synthesis at room temperature at a voltage of 50 V for 60 minutes yields the product with particle size of 40 – 60 nm, which can be used in wide array of applications. This paper also highlights the research gaps for future work and gives recommendations to extend this study particularly for the industrial application of tungsten oxide.
