β¦ Synopsis
Temperature dependence mczurements
(2-77OK) of both the Lifetime of decay and the quantum yield of luminescence for the tris(2,2'.bipyridine)ruthcnium(ll) cation show the emission to originate from several levels. Energy level gaps, rate constants, and quantum yields have been measured for each individual level, and group theoretical symmchy assignments have been made on the basis of a proposed clcctronic coupling model.

Upconversion (UC) has attracted much attention due to its potential applications for photovoltaics, photocatalysis, nonlinear photonics, and so forth. [1][2][3][4][5][6][7][8][9][10][11][12] In principle, two techniques are available for upconversion from a chemist's perspective. The first one is to
