Project 18: Leading the Way: Lighting for Tomorrow (Prof. Delaina Amos, ChE)
Project Description: This student will work with a post-doctoral associate on characterization of novel quantum dot light emitting diodes (QdLEDs). These next generation lighting devices contain novel light emitting materials that are predicted to produce more colorful, less expensive, longer lasting, and high efficiency lights for home and business use. Current energy usage for lighting in the US consumes approximately 20% of our total energy expenditure. If proven effective, these lights are expected to compete with the highest efficiency lights currently available including LEDs, CFLs, and High Intensity Discharge (HID) lamps. The student will be trained in analytical techniques important to the characterization of the lighting devices including Scanning Electron Microscopy (SEM), Fluorescence Spectroscopy, UV-Visible Spectroscopy, and optical microscopy. These analytical techniques are both quantitative and qualitative and allow the student to see the nanodevices at higher resolution as well as provide chemical signatures unique to the materials and devices. Finally, the student will be trained in spectral radiometry in order to actively measure the amount of light emitted. These devices are created as a series of thin layers, and the student will also have the opportunity to both observe and participate in the fabrication of the devices. This close up of novel device fabrication will give the student the opportunity to observe and participate in the research of new materials and fabrication techniques for high efficiency lighting devices. The student will be mentored by a post-doctoral student and Dr. Amos.
