FIG. 1.

(Color online)The experimental setup for both liquid and solid-state quantum yield measurements using either a Hg arc lamp or Nd:YAG laser as the source. The components of this system are as follows: (a) Hg arc lamp, (b) monochromator, (c) iris, (d) focusing lens, (e) light valve, (f) mirror, (g) Nd:YAG laser, (h) mask for the laser beam, (i) variable temperature mounting plate, (j) sample holder, (k) focusing lens, (l) chopper, and (m) detector.

FIG. 2.

(Color online) A schematic of the Nd:YAG laser, which consists of (a) the laser module, (b) temperature set, (c) thermoelectric cooler modules, (d) a water cooling module, (e) a thermocouple, and (f) lens.

FIG. 3.

(Color online) Beam profiles for (a) Nd:YAG laser with and , and (b) high-pressure mercury arc lamp with and . The beam intensities are (a) and (b) . The beam profiles were obtained by reflecting the beam off a white surface onto an Ocean Optics USB4000 spectrometer and analyzed using Igor Carbon Pro fitting program.
