FIG. 1.

Emission spectra of light decoupled from sample edge of Eu–Al/PMMA planar waveguide under cw optical pumping. The concentration of Eu–Al nanocluster is . The pump wavelength and density are and , respectively. The intensity at is ninefold enlarged. The inset is schematic illustration of molecular structure for Eu–Al nanocluster.

FIG. 2.

Integrated emission intensity of transition as a function of excitation-stripe length. Closed circle, open circle, and closed triangle plots denote the data measured at pump densities of 1.55, 0.78, and , respectively. Each curve shows a function obtained from a least squares fitting of experimental data by using Eq. (1) .

FIG. 3.

Emission decay profile of columnar Eu–Al/PMMA sample. Dashed line shows a function obtained from a least squares fitting of experimental data. The light source for excitation pulse was a laser. The wavelength, pulse energy, and duration were , , and , respectively.
