The program is aimed at the measurement and interpretation of optical constants from the lattice vibration absorption region in the IR to energies at least 10 v greater than the first band gap. Reflectance was measured from cleaved faces of single crystals at normal incidence in the 4 to 11.5 ev range, and at an 80 degree angle of incidence with polarized radiation in the 1.5 to 5 ev region. This report includes BAND EDGE EMISSION PROPERTIES OF CdTe, by R. E. Halsted, M. R. Lorenz, and B. Segall, 1961, 20p. incl. illus. table. Contract AF 336168264 To be presented at the International Conference on Photoconductivity at Cornell University, Ithaca, N. Y. on Aug 24-27, 1961. Near band edge fluorescent emission in CdTe is discussed. Longitudinal optical phonon spacing between emission lines was observed at 20 K.
