34. Varying the laser intensity should give an indication of triplet-triplet annihilation, with higher laser intensities giving more excited molecules, and thus intermolecular triplet-triplet annihilation would be more probable. We see no difference in the quenching observed, whether we use very high or very low laser intensities. However, with iridium phosphors bound closely to one another, this experiment is not efficient, because the phosphors are tightly bound, and are not expected to move rapidly. Thus it would be necessary that neighbouring phosphors are excited to allow for triplet-triplet annihilation. This is highly unlikely unless extreme laser intensities were used.
