In systems in atomic and nano scales such as clusters or agglomerates constituted of particles from a few to less than one hundred of atoms, quantum confinement effects are very important. Their optical and electronic properties are often dependent on the size of the systems and the way in which the atoms in these clusters are bonded. Generally, these nano-structures display optical and electronic properties significantly different of those found in corresponding bulk materials. Silicon agglomerates found in Silicon Rich Oxide (SRO) films have optical properties, which have reported as depended directly on nano-crystal size. Furthermore, the room temperature photoluminescence (PL) of Silicon Rich Oxides (SRO) has repeatedly generated a huge interest due to their possible applications in optoelectronic devices. However, a plausible emission mechanism has not yet widespread acceptance of the scientific community. In this research, we employed the Density Functional Theory with a functional b3LYP and a basis set 6 - 31G* to calculate the optical and electronic properties of small (six to ten silicon atoms) and medium size clusters of silicon (constituted of eleven to fourteen silicon atoms). With the theoretical calculation of the structural and optical properties of silicon clusters, it is possible to evaluate the contribution of silicon agglomerates in the luminescent emission mechanism experimentally found in thin SRO films.

Particle Encapsulation in Crosslinked Hydrogel Networks： Particle Distribution Optimization

引用

材料科学与工程（中英文b版） 2012年第10期2卷 539-550页

作者： Karem A. Court Jackeline Jerez Rodolfo J. Romanach Madeline torres-Lugo Department of Chemical Engineering University of Puerto Rico Mayaguez Campus P O Box 9000 Mayaguez Puerto Rico 00681 Department of Chemistry University of Puerto Rico Mayaguez Campus PO Box 9000. Mayaguez Puerto Rico 00681

Particle encapsulation in hydrogel membranes was performed to examine which physical factors are involved in particle distribution within membranes. This investigation focused on the examination of the physicochemical interactions between particles and crosslinked hydrogel networks for the creation of homogenously dispersed particles in a membrane. For this purpose factors such as particle charge, concentration, and membrane charge were examined to ascertain their effect on particle dispersion within the matrix. Anionic hydrogels composed of methacrylic acid (MAA), cationic hydrogels composed of N, N-dimethyl amino ethyl methacrylate (DMAEM), and neutral hydrogels composed of 2-hydroxyethyl methacrylate (HEMA) were utilized to encapsulate functionalized silica particles. Particle distribution was analyzed by Scanning Electron Microscopy and Near Infrared Chemical Imaging (NIR-CI). A new method was developed to evaluate the distribution of particles throughout the membranes. NIR-CI results indicated that neutral membranes with low particle concentration showed better particle distribution.
