Comments on "The future of electroluminescent solids in display applications" and "New display technologies—An editorial viewpoint"

Statements of Gordon and Anderson denying the utility of further research on potential materials for blue light-emitting diodes (LED´s) are contested. It is shown that the dominant luminescence from sometime commercial SiC devices cannot arise from intrinsic recombinations as implied by Loebner, but may indeed involve free-to-bound recombinations at deep levels, as previously suggested. Finally, comments are made about the current state of our understanding of ZnS-powder EL cells.
