Light Scattering and Organic Optoelectronics Research Group

We work in the area of optical spectroscopy, exploring novel light scattering techniques for structural and electronic characterization of organic/inorganic semiconductors, fullerene systems, and organic optoelectronic devices. Our current work includes photophysical studies of blue-emitting organic semiconductors (conjugated molecules and polymers), and nanoscale organic optoelectronics device fabrication and electrical characterization.

Current Research Projects

Tour of the light scattering laboratory

Macro-Raman/PL set up * Spex 1402 (PMT/CCD) * Coherent Innova argon ion Laser (UV and VIS) * Closed Cycle Ref.(11-300 K)	Macro-Raman/PL set up	Micro-Raman set up Renishaw InVia System * 785 nm laser diode * Deep depletion CCD * xyz automated stage	Modulation spectroscopy setup * HeCd Laser * CVI monochromator * Lock-in Amplifier

Tour of the growth/fabrication facility (organic optoelectronics)
This facility is funded by an instrumentation award from the National Science Foundation (DMR-0413601). The system consists of a glove-box integrated spincoater and a thermal evaporator connected by an antechamber. The design of the integrated system is based on the interior area that functions as a clean room [class (10-100)] by a laminar gas flow.

Grad Students: Arif at the spincoater and Vijaya supervising!	M-Braun thin film deposition system-left chamber has the thermal evaporator and the right glove box has a spincoater and a mini-oven.	PLC controller of the system	Thermal evaporator-interior *four evaporation sources * process vacuum ~10^-7 * quartz lamp heater for substrate heating
