^a 6 wt% doped into a thin film of Bebq₂.

^b The lifetime τ ₀ at infinite dilution determined from the linear variation of the observed emission decay rate constant, k _obs, as a function of the concentration of the complex.

^c Value too low to be reported.

^d Value not available from the literature.

^e The work that has not been reported.
