Triplet solvation dynamics in supercooled hydrogen bonding liquids in hard and soft confinements

Experimental Setup (Basic)

The dye is excited to the triplet state by the third harmonic of a pulsed Nd:YAG laser at 355nm. To avoid bleaching of the dye the pulses are attenuated down to 4 mJ. The sample is mounted in a contact gas cryostat and can be tempered in the range from 320K to 77K. The emitted light is collected under 90° to the incident laser beam by a liquid light guide fiber. The output of the fiber is collimated into a grating spectrograph. An Intensified-CCD (iCCD) is used to record the time-resolved emission wavelength of the dye.
