Abstract:
A composition of matter, comprising:a) a membrane compartment in contact with a solid surface, wherein said membrane compartment comprises at least one photon producing agent, andb) an aqueous solution with at least one photon reducing agent, wherein said aqueous solution is in contact with an outer surface of said membrane compartment,wherein said at least one photon reducing agent is substantially impermeant to said membrane compartment,wherein said at least one photon reducing agent has an absorption spectrum that overlaps with the absorption, emission or excitation spectrum of said at least one photon producing agent, andwherein said at least one photon reducing agent is present in said aqueous solution at a concentration sufficient to reduce light emitted from said aqueous solution by at least 10% compared to the light emitted of said aqueous solution in the absence of said at least one photon reducing agent.
