We report on measurements of the absolute efficiency for the resonant energy transfer (RET) from a metal nanoparticle to a semiconductor nanocrystal solid in a near-field regime. Quantitative estimates of the RET contributions independently of the backward charge and energy flow were obtained by using the Sample Transmitted Excitation Photoluminescence (STEP) spectroscopy that measures the percentage of photons absorbed by a metal nanoparticle that decay through exciting an electron-hole pair in the semiconductor counterpart. To ensure that the energy exchange occurs predominantly in the near-field regime, we employed 15-nm spacer-coated Au nanoparticles incorporated within a solid of CdSe quantum dots.
