ABSTRACT OF THE DISCLOSURE A luminescence detecting device including a luminescence sensitive member made of a transparent resin or the like and containing at least two different kinds of organic phosphors dispersed therein. The first organic phosphor is operative to absorb fluorescence from incident radiation such as the index phosphor stripes from a reflex color cathode ray tube, and has a response spectrum which overlaps with the wavelength range of the incident fluorescence. The first phosphor is designed to emit fluorescence in a higher wavelength range upon excitation by the incident fluorescent radiation. The second phosphor is responsive to the fluorescence emitted by the first phosphor since the spectra of the two phosphors overlap. The second type of organic phosphor emits its own range of fluorescence in a particular wave band and can be detected by a luminescence sensing portion of the device to provide a signal which can be used to control the operation of the cathode ray tube.
