Figure 4.9 Schematic energy-level diagram (left) for laser dyes, including the major absorption, emission and loss mechanisms. As an example, the related spectral absorption and emission bands are shown for the laser dye rhodamine 6G (right) the wavelength positions of suitable pump lasers are indicated...

These pilot experiments were joined by the studies on the metastable Xe II, 5p 5d Dt/2 state in Xe" beams, from which the transition to 5p 6p Ps/2 is covered by the spectral range of the then standard laser dye Rhodamin 6G. 

Once formed phosphonium salts could have a significant effect on cellular processes, particularly on mitochondrial function. Ph3PMe has been used as a probe to measure membrane potentials, for instance in thyroid cells lymphocytes Escherichia and human granulocytes The lipid-soluble cation distributes itself across the membrane in accordance with the membrane potential Monovalent lipophilic cations which have significant membrane permeability are concentrated in mitochondria. For instance the laser dye Rhodamine 123 has been used as a specific probe for the localisation of mitochondria in living cells It has also been shown to have in vivo antitumour activity ...
