(a) absorption and (b) emission spectra (see Ref. 5), (c) LED emission, (d) laser emission, and (e) transmission of filter.

FIG. 2.

Test apparatus for saturation and photobleaching measurements. Inset (a) is an example of optode on core POF excited with a blue LED. Inset (b) is a schematic illustration of a core glass fiber tipped with /silicone matrix.

FIG. 3.

Normalized phosphorescence decay of in air at fitted to a sum of two exponents (dashed).

FIG. 4.

Two data sets showing saturation of with excitation where the (diamonds) first set and (squares) second set are for the same optode. Linear extrapolation of the linear response of emission vs excitation power (dashed), expected (dotted), and measured (dash dot) saturation powers are shown.

FIG. 5.

Photobleaching of with of excitation power over with sum of two exponential fit (dashed). Fitted photobleaching lifetimes are 3.24 and with preexponential factors of 0.07, and 0.205, respectively.
