Spontaneous emission enhancement in planar metal-organic structures

We provide an experimental investigation of a Purcell enhancement in a silver-organic periodic structure with an organic material CBP (4,4′-Bis(N-carbazolyl)-1,1′-biphenyl). Were fabricated two structures using a thermal evaporation technique with a different thickness ratio between layers. A rate o...

Summary:We provide an experimental investigation of a Purcell enhancement in a silver-organic periodic structure with an organic material CBP (4,4′-Bis(N-carbazolyl)-1,1′-biphenyl). Were fabricated two structures using a thermal evaporation technique with a different thickness ratio between layers. A rate of a fluorescence intensity decay of the periodic structures was experimentally measured in a near ultraviolet region. We show experimentally, that the rate of CBP molecule fluorescence decay increasing. A maximum registered value of the Purcell factor is close to 10.
