Time-resolved photoluminescence setup

Technical specifications

This set-up provides mapping in the UV-Vis range (270 – 800 nm) and in a time range from 1 ns to 1 ms. It also enables non-time-resolved near-infrared measurements (800 – 1700 nm). It includes the pulsed excitation system for generating transient photoluminescence and the detection system for collecting the photoluminescence signal from the sample. It uses a slit-scan camera to obtain 3-dimensional images (temporal, spectral and luminescence intensity).

For the excitement part:

Laser 100 fs, 1 kHz, amplified Hurricane X Spectra-Physics (pulses of 100 fs at a rate of 1kHz at 800nm for a nominal power of 1W);
OPA and SHG/THG Spectra-Physics housing.

For the detection part:

SDG II Spectra physics, delay generator used for the 0.5 ns – 100 ns range;
DG535 Stanford Research Systems, delay generator used for the 100 ns – 1 ms range;
Princeton Instrument SP 2360 Acton spectrometer;
CCD NIR Princeton Instrument OMA V;
Hamamatsu C7700 slit-scan camera (optimum resolution 5 ps) coupled with an ORCA II CCD camera (1344×1024 pixels) cooled to -60°C.
