Why AgBr shows both frenkel and schottky defect?
because the size of ions are enough to show both defects
Why does AgBr show both Frenkel and Schottky defects?
The radius ratio for AgBr is intermediate. Thus it shows both frenkel and schottky defects. The major defect in AgBr is the Frenkel defect. It has a rocksalt structure i.e. CCP lattice of of Br with atoms of Ag occupying all octahedral holes.Ag moves from octahedral to tetrahedral sites causing only cations to precipitate. Schottky defect arise due to missing of ions from their lacttice point and frenkel arise when the mmissing ions occupy interstitial sites. in AgBr, ag+ ion is small in size and when removed from lacttice point they can occupy interstitial site and therefore show both frenkel and schottky defect. SCHOTTKY Defect in AgBr is exhibited due to precipitation of both Cations and Anions.
Why did they use chemicals and glass plates in early photography?
until celluloid was invented Glass plates were used because it was the only way to suspend the emulsion evenly and allowed light to pass through. It was easier to handle. Some glass plates were large and were put into contact with paper to create a positive image. Chemistry was used to convert the silver halides in the emulsion to visible black metallic silver halides. When light was shone through the glass the black metallic silver halides stopped the light and the paper was exposed where the light pass by the halides. This caused the material being exposed to show a positive image.
