Hyper-Rayleigh Scattering Facility Development
The STC has constructed an HRS apparatus based on a Ti:sapphire pumped optical parametric oscillator. First, the output of a Ti:Sapphire oscillator (Spectra Physics Tsunami) can be used for excitation from 740 to 1000 nm.
Further tunability is achieved by using the oscillator to pump an optical parametric oscillator (Spectra Physics Opal) which provides output ranging from 1.1 to 2.5 nm. This system is now operative, and has been used to provide estimates for approximately 16 chromophores recently developed by researchers involved in the STC.

Facility for Synthetic Scale-up and Purification
For many proposed applications and studies in the STC, reasonable quantities of pure material are required. A new shared synthetic scale-up and purification facility has been constructed recently in the Department of Materials Science and Engineering (480 sq. ft.) at UW to provide synthetic capabilities for preparation of materials on quantity scales and purity compatible with device fabrication.
The facility is equipped with fume hoods with vacuum and gas lines, various scale-up organic solvent distillation and purification systems, analytical and preparative mode gel permeation chromatography systems with various columns (Waters Breeze HPLC System, Waters Corporation), medium pressure silica-gel based chromatography columns, and large scale laboratory glassware in addition to more common organic laboratory equipments such as vacuum and drying ovens, recirculating chillers, refrigerator/freezer, rotary evaporator, balances, stirrer hot plates, and chemical and solvent storages systems. To complete the facility, large scale reaction and purification assemblies and high vacuum purification systems are still required.
By integrating the functions of the existing synthetic and material characterization capabilities of various laboratories and departments of the STC team members, we are planning to improve the facility to establish a practical synthetic scale-up and purification capabilities of the STC available to all team members.

Organic Electronics Facility
The Center has developed a state-of-the-art facility for the purification of organic materials, the fabrication and testing of organic photonic and electronic devices. The facility is comprised of an automated high vacuum deposition system with four organic sources and two high power sources for metals and oxides (co-deposition capabilities). It is integrated with a double glove box (one dry and one wet with integrated spin-coater) that enables the fabrication and testing of new devices in inert atmosphere. A second glove box is equipped with a microprobe station and a semiconductor parameter analyzer.
The facility is fully equipped for the testing of organic light-emitting diodes, organic field-effect transistors, and organic solar cells.
