The luminescence of the compounds 2CdO·B2O3, 3CdO·2B2O3, and 2CdO·3B2O3 has been investigated under 2537Å radiation and cathode ray excitation for a wide range of manganese concentrations. Under 2537Å radiation, each compound emits in the orange or orange-red with a peak intensity near 6200Å at room temperature. For each composition there is a broad maximum in the relative intensity between MnO concentrations of 0.1-1%. The 3:2 compound appears to yield the brightest phosphor, but the 2:1 compound is only slightly less intense for equivalent manganese additions. The 2:3 compound yields only half the relative brightness of the 3:2 compound for equivalent manganese concentrations.Under cathode ray excitation, the 2:1 and 3:2 compounds fluoresce orange and the 2:3 compound fluoresces green for manganese concentrations between 0.01 and 2%.
