Abstract:

Disclosed is a high reflectivity integrating cavity and device to amplify and detect luminescent emissions produced by small concentrations of materials to be analyzed. Femto or nano molar concentrations of a material can be placed within the high reflectivity integrating cavity. At least the interior surface of the high reflectivity integrating cavity can comprise a coating that, at a designated wavelength of electromagnetic radiation, is transparent and non-absorbing to such designated wavelengths of electromagnetic radiation. In addition to the isotropic field induced by the interior surface of the high reflectivity integrating cavity, the high reflectivity of the interior surface of the high reflectivity integrating cavity leads to very large effective optical path lengths within the interior of the high reflectivity integrating cavity, thereby amplifying the luminescent emissions produced by the sample.
