[Also in Division C4] A light-emitting device comprises a body 1 of semi-conductor material having two regions 2, 3 containing deep-lying traps for positive holes and electrons, respectively, ohmic contacts 4, 5 to the two regions allowing a bias 6 to be applied across the crystal. Both regions are initially highly resistive (> 10<SP>10</SP> # cm.), but illumination with light sufficiently energetic to bridge the forbidden energy gap produces electron-hole pairs throughout the crystal, subsequent trapping resulting in N-type and P-type conductivity in the regions 2, 3, respectively. Recombination radiation, preferably in the visible region, occurs at the PN junction thus formed. The traps may be re-emptied by illumination with light of lower energy. The preferred material for the body 1 is of the cadmium-zinc-sulpho-seleno-telluride group, e.g. ZnSe x Te 1-x , but III-V compounds containing Al, Ga, In, Tl, B, N, P, As, Sb, or Bi, or doped diamond may also be used. ZnSe x Te 1-x  may be subjected to Al diffusion to produce the region 2, the region 3 subsequently being produced by firing in contact with gaseous or liquid zinc. Alternatively a crystal of the same material may be immersed in a bath of 99À9 mol. per cent Zn and 0. 1 mol. per cent Al at 950‹ C. for 16 hours, the 0. 1 mm. thick Al-diffused layer subsequently being ground or etched off all but one face.
