Electrons energy, ruby

A surprising observation was made in the first experiments on the flash photolysis of CdS and CdS/ZnS co-colloids Immediately after the flash from, a frequency doubled ruby laser (X = 347.2 nm photon energy, = 3.57 eV) the absorption spectrum of the hydrated electron was recorded. This species disappeared within 5 to 10 microseconds. More recent studies showed that the quantum yield increased... 

Figure 6.8 The Sugano-Tanabe diagram of a 3d electronic configuration (C/5 = 4.5). The two vertical lines correspond to the DqlB values in the crossover and for the ruby crystal (see the text). The inset shows the energy-level diagram for strong crystal fields.

CH+tAljOs Ruby System. The transition-metal Cr ion has a electron configuration, and when substituted for an AF ion in the AI2O3 lattice, the oxygens produce a near-octahedral crystal field that splits the five degenerate (/levels into and t2g levels. The lowest energy states derive from the and (/2P e confignrations of the three (/electrons...
