ABSTRACT:
A thin layer bearing a luminescent dye is superposed over a solid state imaging device and converts light energy, say in the blue range to longer wavelength light energy, say in the yellow-orange range. By so using a luminescent dye, the solid state imaging device's greater sensitivity at longer wavelengths is, in effect, substituted for the inferior sensitivity that typically exists for blue light, thereby upgrading the blue response of the device.
