Fluorescent compounds which are conjugates of a biologically active moiety and an arylidene dye moiety. The compounds have a large Stokes shift and are useful in applications such as biological diagnostic elements.

Fluorescent conjugates and biological diagnostic assay system

The blue light response of solid state photosensitive devices such as silicon based charge-coupled devices (CCDs), charged-injection devices, photovoltaic devices and the like is enhanced by applying to the surface thereof a thin layer which includes a first, or donor, dye which absorbs efficiently in the blue region of the spectrum and a second, or acceptor, dye which absorbs efficiently in the green region of the spectrum, there being substantial overlap between the emission spectrum of the donor and the absorption spectrum of the acceptor. The relative concentrations of the dyes are controlled such that the donor dye transfers energy nonradiatively to the acceptor dye which is caused to fluoresce thereby emitting light in the region where the device has substantial photoresponse.
