ABSTRACT OF THE INVENTION A method for determining pH or pCO2 using luminescent lifetimes and energy transfer in which an energy transfer donor- acceptor pair is exposed to a sample to be analyzed, the donor of the donor-acceptor pair being photoluminescent and the acceptor of the donor-acceptor pair being sensitive to the pH or pCO2 of the sample. One or both of the donor-acceptor pair may be bound to a carrier. The sample is irradiated and the resultant emission detected. By measuring the apparent luminescent lifetime, the pH or pCO2 Of the sample can be determined.
