This paper presents a comprehensive investigation into the optimization of exciplex emission in organic light-emitting diodes (OLEDs). Through a systematic exploration of various combinations of hole-transporting materials (HTMs) and electron-transporting materials (ETMs), we elucidate critical factors influencing exciplex formation and its impact on OLED performance.

- Polysaccharides are macromolecules, polymers with a few hundred to a few thousand monosaccharides joined by glycosidic linkages. - Some polysaccharides serve as storage material, hydrolyzed as needed to provide sugar for cells. - Other polysaccharides serve as building material for structures that protect the cell or the whole organism. - The architecture and function of a polysaccharide are determined by its sugar monomers and by the positions of its glycosidic linkages.

Polymerase Chain Reaction is widely held as one of the most important inventions of the 20th century in molecular biology. Small amounts of the genetic material can now be amplified to be able to a identify, manipulate DNA, detect infectious organisms, including the viruses that cause AIDS, hepatitis, tuberculosis, detect genetic variations, including mutations, in human genes and numerous other tasks.

Solubility parameters of carbon quantum dots (CQDs) are important physical properties to deploy CQDs in various applications such as organic light emitting diodes (OLEDs), light-converting materials in LEDs, and photoluminescent sensors for metal ion detection. Because of the low toxicity and tunable emission most CQDs have been designed to be water-soluble and biocompatible; oilsoluble CQDs that are essential for OLEDs are not yet explored.

The objective of this project was to develop \(Ti{O_2}\) based multifunctional substrates through silver decoration, while simultaneously enhancing the photocatalytic performance of \(Ti{O_2}\) in the substrate. Employing Ag nanoparticles introduced additional functionality to the system, namely surface-enhanced Raman scattering (SERS), thus enabling the detection of trace amounts of organic molecules prior to their degradation, all with the same substrate.
