Sub-micron Photoluminescence Mapping with LabRAM HR-PL
Photoluminescence (or PL) is a spectroscopy technique providing information on bandgap, crystal structure and defects of semiconductors and many nano-materials.
A PL microscope is a laser based instrument measuring optical luminescence emission from materials excited with energy above their bandgap.
HORIBA Scientific micro-PL mapping systems are used to image small features made out of those semiconducting materials, such as diodes or nano structures like Gallium Nitride (GaN) or Silicon (Si) nanowires, Carbon Nanotubes etc…
Since the Photoluminescence Microscope systems are based on HORIBA Scientific leading Raman spectrometer systems, Raman studies can also be conducted on the same instrument.

Photoluminescence Mapping systems from HORIBA Scientific are used for research or production environments, and can be fitted with temperature controlled cells (LN2 or He cryostats) to measure photoluminescence emission at low temperature. This technique usually helps getting clearer information, from sharper spectral features.
This system is also used for:
- Full Wafer mapping, PL Mapper System
- Photoluminescence studies of Carbon Nanotubes
- Mapping of nano-materials such as Gallium Nitride (GaN) nanowires or Silicon (Si) nanowires
- Photoluminescence and Raman of III-V devices such as AlGaAs / InGaAs diodes
- Raman and Photoluminescence studies of semiconductors
- Low Temperature Photoluminescence (PL)
