Recently, we purchased a set up our own device fabrication facility, in which we fabricate and test our OLEDs. It consists of the interconnected glove-boxes: one holding the evaporating chamber with 8 sources, second wet processing, and third for for device testing. We use brightness light distribution characteristics system by Hamamatsu, which measures both the optical and electrical properties of an OLED at the same time. Hamamatsu developed this system in collaboration with Adachi laboratory at Kyushu University.
As we are moving toward micro- and nano-photonic devices, we realized we need tools that would allow observing/imaging the devices, materials and features on relatively small scale. We have acquired an Olympus FluoView 1000 confocal microscope equipped with a lifetime-imaging (FLIM) and with fast-correlation spectroscopy (FCS) modules by Picoquant.
The Group owns and operates the following resources located in our laboratories (517,520,122 Physical science building and 026 Overman Hall): time-correlated single photon counting fluorimeter (Edinburgh) for recording steady state and time-resolved spectra. The combination of the three lamps allows accessing lifetime 100 ps - 10 s. The solid-state steady-state luminescence is measured using the integrating sphere (Labsphere) connected to an Andor spectrometer and camera by an optical fiber and laser diode excitation sources. In the future, the integrating sphere will be housed in the dedicated inert atmosphere glovebox. This will allow us recording room-temperature luminescence from triplet emitters. Fluorescence-based micro-imaging is performed using fluorescence microscope (Dialux, Leitz) with color CCD camera (Pixera). UV-vis spectra are recorded using double-beam (HITACHI) or diode-array (HP) spectrometers. The DFT calculations are carried out on three dedicated PC workstations and Dell PowerEdge III server. Surface topology is studied using a surface profilometer (KLA Tencor). We also own an electrochemistry setup with electrochemical quartz-crystal microbalance (EQCM). Our group's lunch nook has a fridge and microwave (to nuke the food) and fire-extinguisher (necessary equipment).
