Welcome to the Stamplecoskie Group
The optical and electronic properties of materials can be readily tuned through composition, and even size/shape. This is especially true for nonmaterial's like metal particles and quantum dots. For example, both of these materials can display anomalous fluorescence, that can be tuned by simply manipulating the exact size of the particles.
When particles are very small the exact number of atoms and ligands is extremely important in dictating optical properties. In the example provided below, four different sizes of thiol protected clusters display drastically different absorption properties, leading to different absorption of solar radiation.
Our broad goal is to develop new photonic materials with tunable optical properties for application in several focus research fields: light-harvesting and solar energy, advanced optical electronics, chemical sensing and biomedicine. The engineering of new photonic materials relies heavily on fundamental understanding of materials properties, often referred to as the 'structure-function relationship'. In the pursuit of novel photonic materials, we foster a culture of innovation and excitement for understanding materials at the molecular level and using this understanding to drive innovation.
