External Quantum Efficiency (EQE) Consists on a custom-built setup. Light source: a stabilized xenon lamp or supercontinuum LASER. Monochromator (Horiba microHR). 1nm spectral resolution. A beamsplitter (Thorlabs BPD254-G) allows for the excitation light to simultaneously illuminate the sample and a photodiode connected to a power meter (Thorlabs S120VC & PM100A). Current is acquired using […]

Four gloves box contains an integrated spin coater, a blade coater and one precision balance. Three glove box is for dry processes, and includes a metal evaporator with two […]
For optical spectroscopy measurements at very high hydrostatic pressures up to 25 GPa (1 GPa= 10.000 bar) we employ a gasketed diamond anvil cell (DAC) of Syassen/Holzapfel type and a liquid pressure transmitting medium (typically a 4:1 methanol/ethanol mixture). High pressure experiments can be carried out also […]
The micro-Raman setup consists mainly of a high-throughput, high-resolution Jobin-Yvon LabRam HR800 grating spectrometer combined with a confocal microscope for optical studies using diverse experimental techniques like Raman scattering and photoluminescence (PL).
