Paper Abstract

The photoluminescent properties of an optical microcavity formed by a single layer of PPV film sandwiched between a quarter-wavelength distributed Bragg reflector and a metal Ag reflector was studied. The significant microcavity effect was observed. (1) The PL emission spectrum of PPV film is a wide band spectrum with two peaks at 510 nm and 550 nm, respectively. The PL emission spectrum of the microcavity shows 2 peaks, which is at 564 nm and 599 nm, respectively. The FWHM of the narrowed emission spectrum is 7 nm. The PL emission intensity of the microcavity at the resonant mode of 564 nm is enhanced by 19 times. (2) It was found that the peak of the microcavity is blue-shifted with the decreasing of emission intensity obviously when the detection angle is increased. We consider that this is a novel phenomenon and worth investigating further.
