Research on white LEDs in College of Electrical Engineering and CS

I was sponsored by OU during the 2017-2018 school year to conduct research on LED phosphor coatings with the College of Electrical Engineering and Computer Science. In a broader sense, this research aimed to improve the quality of white LEDs. More specifically, a white LED consisting of a blue LED with a novel phosphor coating was characterized. I secured 3K of funding for the project through two internal grants. Funding was used to buy various blue LED modules, testing equipment, and phosphor samples. Testing began by characterizing the blue LED modules before coating them with phosphor. The LEDs were wired to a power supply in a dark environment and then, using an Oceanview Spectrometer and its companion software, the LED's spectrums were recorded. While time constraints prevented the completion of this research, I was able to present my research and results at the 2018 Student Expo.

Demonstration and explanation of different varieties of LEDs to judges at the Student expo.
Explaining how research on improved phosphors would reduce raw material consumption as well as create better quality and tunable wLEDs
Poster used during the student research expo in 2018. Goes through testing methods, results, and impact. This research revolved around creating a phosphor which could be tuned to a superior white light. I learned about optoelectronic specifics such as spectral data and CIE chromaticity charts.
3D printed prototype for the custom sample holder. Used to test fit the Hall sensor and magnets.
Machined sample holder. A slot was implemented to adjust the height of the magnets relative to the sample.
Assembled sample holder with two neodymium magnets.
