摘要：

We investigate the role of quantum efficiency in determining the extent to which the local photonic environment may alter the spontaneous emission rate of organic dye molecules with broad luminescence spectra. Comparison of theory with experimental results shows that the quantum efficiency is a key determining factor in such control, low quantum efficiencies leading to poor control. These results help establish a firm basis for characterising near-fields in nano-optics and controlling fluorescing species.
