Abstract

The parent specification described converter for a radiation receiver, consisting of a matrix in which >=2 elements (a) working in cascade are homogeneously dispersed; i.e. elements (a) receive energy of smaller wavelength and form energy of increased wavelength, which is transmitted. The absorption and emission spectra of elements (a) overlap in building the cascade. The novelty is that elements (a) are Pr, Sm, Eu, and/or Nd, or a cpd. of these elements, or a uranyl ion, whereas the matrix is inorganic. The pref. matrix is solid, consisting of a phosphate glass or borosilicate glass, or a transparent quenched chemical element or alloy; and the concn. of elements (a) in the matrix is 0.2-5.0 wt.%. Alternatively, the matrix may be liq., esp. an aq. phase (b), contg. the nitrates, chlorides or fluorides of the above elements (a). Used esp. with photoelements.
