Silicon nanocrystals (SiNCs) have unique properties manifested at nanometer dimensions. The optoelectronic properties of silicon nanocrystals depend on size and surface chemistry. Investigation into the electronic and optical nature of SiNCs can facilitate the synthesis of efficient optical and...
Improving the spectral stability of poly(9,9-dioctylfluorene) (PFO) through the use of aromatic ethersDownload
Aromatic ethers (AEs) have been combined with poly(9,9-dioctylfluorene) (PFO) to improve spectral stability in PFO systems. Compared to neat PFO, PFO/AE blends were found to have decreased ‘g-bands’ following heating in air. Some were further found to induce and maintain β-phase emission. The...
Group 14 semiconductor nanocrystals exhibit size-dependent optoelectronic properties through the influence of quantum size effects, notably intense photoluminescence (PL). A crucial step toward the realization of their technological potential is the development of effective methods to control the...
Synthesis and Properties of Graphyne Model Compounds and an Electrochemical Study of Substituted PentacenesDownload
The work described in this thesis focuses on two central topics: (1) the synthesis of carbon-rich macrocycles as model compounds of the carbon allotrope graphyne and the study of their electronic properties, and (2) the electrochemical investigation of the properties of substituted pentacene...
Silicon nanocrystals (SiNCs) are a biocompatible and elemental abundant sub-class of quantum dots. Since SiNCs were prepared, many efforts have been made to get a tunable size and rich surface chemistry that greatly expanded their applications from electronic devices to target treatments. Among...
Silicon nanocrystals (SiNCs) have been explored as active materials in a variety of prototype applications including photovoltaics, electronics, photonics, and sensors based on their optical and electronic properties. Using SiNCs are appealing because their source material (i.e., silicon) is...
