This report covers in detail the solid state research work at Lincoln Laboratory for the period 1 August through 31 October 1969. The topics covered are Solid State Device Research, Materials Research, and Physics of Solids. Accepted for the Air Force Franklin C. Hudson Chief, Lincoln Laboratory Office

A new Ce(3+)-activated thiosilicate phosphor, BaLa2Si2S8:Ce(3+), was synthesized by using solid-state methods in a fused silica ampule and found to crystallize in the structure type of La2PbSi2S8. The crystal structure has been characterized by synchrotron X-ray diffraction and refined with Rietveld methods. This novel cyan-emitting phosphor can be excited over a broad range from UV to blue lig...

Nanostructured Ni2As2O7 semiconductor samples were synthesized by a solid state method among As2O3 and Ni(NO3)2.6H2O raw materials at 650 °C (S1) and 750 °C (S2) as reaction temperatures. The synthesized nanomaterials were characterized by powder X-ray diffraction (PXRD) technique and F...

in this work, all-solid-state potentiometric pvc membrane sensor was introduced for fast andsimple monitoring of mercury ions in waste water samples. the all solid sate electrode is made based on aconductive composite of graphite, reduced graphene oxide, epoxy resin on a copper wire. a thin layer pvcmembrane is then coated on the surface of the new conducting transducer. pvc membrane is compose...

“malakoot” story (literally celestial kingdom), the only novel written by bahram sadeghi, is one of the memorial work that has been witten under the influence of “boof-e-koor” story (literally blind owl) written by sadegh hedayat by a distinctive style and during a specific period of time. aside from unique content of this story, form and structure of this work are also remarkable and marvelous...
