OLED research

PLATTEVILLE, Wis. — University of Wisconsin-Platteville students Ross Johnson, from Appleton, Wis. and Yilda Torres from Margarita Island, Venezuela will be recognized for their undergraduate research at an annual event at Posters in the Rotunda at the state capitol in Madison, Wis. At this event, selected participants have the opportunity to present their research to the public and their state representatives.

“It’s very exciting,” said Johnson, “I see it as an honor to be able to go out and share what we’re doing at UW-Platteville.” Both Johnson and Torres are doing research with fabrication of thin film organic light-emitting devices (OLEDs) under the supervision of Dr. Soma Chattopadhyay of the chemistry department. They are exploring the working principles behind the displays used in digital cameras, mobile devices and portable media players among others.

Johnson said his research entails varying the chemical composition of the miniature OLED device and testing if it would emit light when hooked up to a circuit. “It’s a bummer when you spend hours working on a device and you plug it in and it doesn’t work,” said Johnson. “Understanding why an OLED can fail was critical. By addressing the underlying issues, I can successfully fabricate OLEDs that will emit light every time.”

Torres said her research focuses on other materials that can be used for fabricating OLEDs. “I am trying to figure out the correct ratio of mixing two compatible chemicals for the device so that light will be emitted when an electric current is passed,” said Torres.

As an international student, Torres said she is excited to experience something that she may not be able to in Venezuela. “I feel honored to be a part of an event like this. Opportunities such as this are not common in my country and I am proud to represent my university with my research partner in the state capitol building,” said Torres. “It feels good to realize that the university acknowledges international students for academic events like this as well.”

The opportunity for Johnson and Torres to present their research on miniature OLEDs and how they emit light will take place on March 12 from 8:30 a.m. to 3 p.m. Johnson says that he is most excited for the opportunity to present to policy makers and show the hard work that was put into his research.

Posters in the Rotunda is an opportunity for students and their faculty advisors across the UW System to present outstanding undergraduate research of important topics to state legislatures, state leaders, UW alumni and the public.

Anyone interested in viewing the research presentation of Torres, Johnson and all other participants from the UW-System are welcome to attend the event.
