Notes:
A quantum-mechanical approach for surface-enhanced optical processes is given, which may solve an old controversy regarding the surface enhancement mechanisms: The present formalism contains three terms: The first is equivalent to the classically derived electromagnetic enhancement; the second represents a loss term due to a competitive dipole–multipole and dipole–electron-hole pair coupling; and the third reveals an additional energy transfer induced gain for excitable molecules. Thus, the total pure surface enhancement can be much greater for "colored'' species than for transparent ones.
