Abstract
A sensor and a method for using the sensor to determine the concentration or partial pressure of oxygen in a fluid media is provided. The sensor includes a light modifying medium containing a luminescent dye which is accessible to oxygen. The luminescent dye contains a hexanuclear core of molybdenum, tungsten or mixtures thereof having 14 coordination sites, wherein each site is occupied by a ligand. The sensor also includes an apparatus capable of transmitting and collecting light to and from the light modifying medium.
