Notes:
A versatile instrumental setup for time-resolved emission spectroscopy under variable pressure (1 atm–11 GPa) and variable temperature (77–400 K) was described. This setup, consisting of a diamond (or sapphire) anvil cell, was successfully interphased to a conventional fluorescence spectrometer, a gated diode-array system with nanosecond laser-pulse excitation, and a photon counting system excited with a cw YAG/dye laser system. The form of the sample for measurements can be either solid or liquid. Furthermore, the anvil cell can be used for IR spectroscopy by means of a FTIR spectrometer as well as for qualitative absorption spectroscopy. The performance was checked with a number of examples such as pressure and temperature effect on the time-dependent shift of emission from Ru(bpy)2+3 in viscous solution, pressure effect on a solid binuclear complex of platinum, and fluorescence behaviors of several organic molecules. Scope and limitation of this novel setup were discussed.
