We find that unicolour or matching emission wavelength materials can be prepared through cation-engineering with the partial substitution of formamidinium for ethylenediammonium to generate “hollow” formamidinium lead bromide perovskite nanocrystals; these materials can be successfully printed into ...
which consist of patterned perovskite nanocrystals on a transparent film, convert light from different directions into luminescence signals of different colours, which can be detected by a colour CCD. UV–vis, ultraviolet–visible light.b, The working principle of light-field...

The second silver deposit may be replaced by mercury, copper or lead. The first silver deposit may be converted to silver iodide and the emulsion redeveloped, after exposure to light with a developer which does not reduce silver iodide. The dyestuffs used may be Chorazol Sky Blue FF or ...
The following substances are stated to be usable in the fluorescent screens 6 when the exciting radiation comprises X-rays: silicates, selenides and sulphide of zinc, leadbarium sulphate, calcium tungstate, sodium iodide activated with thallium, sodium chloride with 10 per cent silver chloride, ...
lead iodidesThe electron spin resonance spectra of single crystals of two of the planar lead halides, chloride and iodide, irradiated at liquid nitrogen temperatures with 纬-rays from a cobalt source, have been investigated at 9.5 Gc sec. In both halides the spectrum as observed at low ...

Instead of zinc hydroxide, lead sulphate, calcium phosphate, or lead iodide (which may be useful as a colour filter) may be used. A particular form of material for exposure through the support comprises a celluloid support, a layer of gelatin containing zinc hydroxide in colloidal state, an ...
Print (a) is toned yellow as by bleaching with lead acetate and potassium ferricyanide and toning with potassium chromate or bichromate ; print (b) is toned magenta as by dye toning, or by converting the silver into a copper salt, or silver iodide, or mercuric silver chloride, and toning...
