The invention provides a lighting device comprising a light source and a light converter, wherein the light source is configured to provide light source light, wherein the light converter comprises a donor luminescent material able to convert at least part of the first light source light into donor light, and a acceptor luminescent material, wherein the donor luminescent material and acceptor luminescent material are configured as donor-acceptor luminescent materials which, upon excitation of the donor luminescent material by the light source light provide acceptor light having an acceptor light spectral distribution different from a donor light spectral distribution of the donor light, wherein the light converter further comprises a periodic plasmonic antenna array configured to enhance generation of said donor light, and wherein the lighting device is configured to provide lighting device light comprising said donor light and said acceptor light.
