Basically without math, certain metals have elecrons that are "free" silver is one of these metals. These free electrons are necessary for a condition called a surface plasmon to exist. Now silver particles in an aqueous solution will have two parts to its refractive index, that of the water and that of the silver nanoparticles. Next is the interaction of light. Photons can be thought as particles or waves, in this case we will think of them as waves. When an electromagnetic wave interacts with the surface plasmon mode it causes the free electrons that are part of the surface plasmon to oscillate, usually in anti phase to the electromagnetic wave. This essentially causes certain wavelengths of light to be blocked from propagating, causing them to be reflected and giving the colour that you see.
Im actuallydoing some research on silver nanoparticles at the moment, and we can change this colour from yellow to almost anything that we want. For a yellow colour we see a plasmon resonance peak ca. 420nm but based on the size and shape of the silver nanoparticles we can tune the plasmon resonance peak.
Mie theory can be used to calcuate the extinction co-efficents. The reason why this is also called the surface plasmon is that the light waves will not penetrate more than 50nm so the interactions at the surface are the most important.
brown, red, yellow , in case of gold its 5% tolerence, silver 10% tolerence, no color 20% tolence..
red (rare), metallic green, blue, light blue, brown, lime green, yellow, silver, black, gray, purple (rare).
yellow
silver is the color that is generally used.
470K ohm at 5% tolerance
An aqueous solution of silver ions (Ag+) typically appears colorless. However, if there are silver nanoparticles present in the solution, it may show a yellow hue.
Silver iodide is typically a yellow or light yellow color.
ZnO appears yellow upon heating due to the formation of zinc oxide nanoparticles. The optical properties of the nanoparticles can cause a shift in the absorption spectrum, leading to the yellow color. This change in color is often attributed to the quantum confinement effect that occurs at the nanoscale level.
It has white color with yellow shades
gold
Mixing yellow and silver together will not create a new color; instead, the colors will remain separate. Yellow will maintain its hue, while silver will retain its metallic appearance.
White or Silver
Silver chromate is a yellowish-white or pale yellow color.
Silver chromate has a brown red colour
The silver turned yellow after cleaning because it reacted with sulfur compounds in the air or in the cleaning agent, forming silver sulfide, which has a yellow color.
I think it's yellow...pinkHis favorite color is yellow...not pink. The reason his favorite color is yellow is because it's the color of his favorite flower.black and purple
Some are silver, and some are yellow.
