Color Film>Silver Layers>Nanoparticle by development>Resonance>Better colors

[Mustafa Umut Sarac]

Does anyone tried to develop color film silver layers to produce different shape and size nanoparticles to resonate with light amd produce purer colors at the end ?

That can be done on dye transfer to trichrome , coloring the bw film.

If no one tried this or invent that I name that process Turkevichochrome

Unless my memory fails me I believe one of our leading intellectuals created Nanonanonano in late 1978.

Perrault Method[edit]
This approach, discovered by Perrault and Chan in 2009,[22] uses hydroquinone to reduce HAuCl4 in an aqueous solution that contains gold nanoparticle seeds. This seed-based method of synthesis is similar to that used in photographic film development, in which silver grains within the film grow through addition of reduced silver onto their surface. Likewise, gold nanoparticles can act in conjunction with hydroquinone to catalyze reduction of ionic gold onto their surface. The presence of a stabilizer such as citrate results in controlled particle growth. Typically, the nanoparticle seeds are produced using the citrate method. The hydroquinone method complements that of Frens,[17][18] as it extends the range of monodispersed spherical particle sizes that can be produced. Whereas the Frens method is ideal for particles of 12-20 nm, the hydroquinone method can produce particles of at least 30–250 nm.Not only on this method usin some micro organisms we can also synthesis the gold nanoparticles

There are several wet chemical methods for creating silver nanoparticles. Typically, they involve the reduction of a silver salt such as silver nitrate with a reducing agent like sodium borohydride in the presence of colloidal stabilizer. Sodium borohydride has been used with polyvinyl alcohol, poly(vinylpyrrolidone), bovine serum albumin (BSA), citrate and cellulose as stabilizing agents. In the case of BSA, the sulfur-, oxygen- and nitrogen-bearing groups mitigate the high surface energy of the nanoparticles during the reduction

I know what you mean and it is old technology but IMHO no one treat film to resonate at the end.

So what you'd need is a chemical, or actually chemicals, that not only react to light in the way that silver nitrate does, but also have bond-lengths such that each different chemical only reacts to a certain wavelength of light.
Presumably, this would mean that once a photon of a certain wavelength is absorbed by such chemical, it breaks the bond and the chemical transforms into something else, and no further photons can be absorbed by this bond.

So you'd need, say, 3 different chemicals that contain bond lengths of 680nm for red, 520nm for green, 450nm for blue, that would break or otherwise transform when hit with a photon of that wavelength, then the resulting chemical left would be developable into something of that colour (or its inverse for negatives). For even more accurate colours, you could add in more chemicals at something like 700nm, 600nm, 480nm, or 400nm.
All of these would presumably be coated in a single coating if they could then be directly-developable into colour, or they'd still be in layers if they had to develop something with dye-coupling (as I understand colour films work now).

Definitely possible, how long have you got to research different chemicals? Could take rather a long time to find them...

ps, I have read about gold particles being bonded directly to half-helices of DNA as a method of DNA testing: when they are put into a solution containing the other half of the DNA that directly lines up, the DNA joins together, the gold particles are thus a known exact distance apart, the resulting structure absorbs an exact wavelength of light and the solution changes colour. Thus, if the solution is the correct colour, the DNA samples match, if the samples don't match then the DNA doesn't join up correctly, and the solution is the wrong colour.

In a similar way, you could bond gold to specifically-tailored DNA to keep the gold particles an exact distance apart and absorb exactly the right wavelengths of light. How you get from there to a developable image I have no idea, but it's a start.

Dr Croubie ,

Your post reminds me the answers given to my question where titanium dioxide replaces silver at emulsions.
First of all , I may want to learn do we understand each other well and do you have knowledge on growing silver nanoparticles and their resonance with light ?

thank you

[Dr Croubie]

Unfortunately no, my degrees are in Electronic Engineering and Economics. But I do understand a fair bit of science and chemistry stuff too, just from high school and first-year uni, and reading things that interest me. My sister has an MSc Chem, I'll ask her if she knows anything when London wakes up.

 

[Mustafa Umut Sarac]

I bet she has a complete idea .

If you look in to articles , I have an attemp to that problem last year. I was thinking to make inkjet colors if honestly talking is needed but tonight I realized to use that technology on films.

(there was a url link here which no longer exists)

Thank you.
