Welcome to Laboratory Room 3rd Floor!
Laboratories in the east wing contain ample resources for cutting-edge research and include four vacuum deposition systems and an organic synthesis room that can accommodate up to 30 people.
| Deposition system | |
|---|---|
 The lab’s first deposition system, which has been with us every step of the way since the very beginning. It is still going strong! |
 Devices with high reproducibility can be fabricated and studied by processing at vacuum levels of 10-5 Pa in this deposition system designed by one of our lab members. |
| Streak camera | Absoption&emission |
 Measuring the fluorescence lifetime of organic thin films gives insight into the mechanisms of radiative exciton recombination and TADF. |
 Equipment for measuring fundamental optical properties of materials, such as UV-Vis-NIR absorption spectra, light emission spectra, and emission lifetime, are available. |
| Synthesis lab | |
 The spacious synthesis laboratory has numerous workstations all enclosed in fume hoods (Dalton). GPC and LC-MS equipment are installed for the chemical analysis and purification of organic compounds. |
 |
| Optical properties lab | |
 EL device emission patterns and laser-excited emission spectra of films can be measured to understand molecular orientation. |
 Ellipsometer The molecular orientation in ultrathin films can be evaluated by measuring the refractive index anisotropy. Measurements can also be made in-situ during deposition. |
| Transient absorption measurement system | Train sublimation purifier |
 With this system, the excited-state absorption spectra of materials can be measured, and the mechanisms controlling exciton quenching under high current flow can be investigated. |
 Organic semiconductors can be refined to high purifies by sublimation. |
