Spectroscopy & Measurement
This capability area underpins the measurement of the physical properties of excitons, including energy, lifetime, transport and dissociation
The centre includes capabilities for:
- Ultrafast exciton generation across the UV, visible and NIR spectral regions.
- Time resolved and/or spatially resolved detection of both exciton emission (photons), spin-state, transport and exciton dissociation products.
- Single molecule/nanoparticle detection up to bulk, film, or ensemble samples.
- Laser excitation in the ns-ps-fs regimes across UV-visible-NIR spectrum
- Time-correlated single photon counting (picoseconds-nanoseconds)
- Visible/IR femtosecond transient absorption spectroscopy
- Femtosecond fluorescence (upconversion, Kerr gate)
- Femtosecond multiple pulse photon echo spectroscopy
- Nanosecond flash photolysis
- Time-resolved fluorescence imaging (FLIM)
- Total internal reflection fluorescence microscopy
- Super-resolution optical microscopy techniques (STED and SIM)
- Single molecule and nanoparticle spectroscopy
- Confocal and Dark-field microscopy
- Scanning near-field optical microscopy (SNOM)
- Solar simulator
- Low temperature cryostats (liquid nitrogen/helium)
