Radiative lifetime of periodically arranged luminescent rods in a waveguide structure is measured with an optical Kerr gate technique. The period of the structure was chosen to be around twice of the wavelength of the exciton luminescence. The rods are made of (C6H5C2H4NH3)2 PbI4, which has a large exciton oscillator strength by virtue of the dielectric confinement effect. In spite of the expectation of a considerable shortening of the radiative lifetime, it was observed to be slightly longer under our conditions.
