Phosphorescent Pigment has an unique property. Due to this property
these pigments can glow even in the dark. Therefore, these pigments are also
called as "glow in dark" class pigments.
Common pigments used in phosphorescent pigments include very smooth crystal
particles of zinc sulfide and strontium aluminate. To stimulate the zinc
sulphide crystal, some quantity of copper is added with it. As a result, the
pigments of Phosphorescent will give the attribute to absorb light and emit
this absorbed light for a longer period of time. The emitting process of
absorbed light is called as Phosphorescence.
Phosphorescence is a specific type of
photoluminescence related to fluorescence. The emitting brightness or
phosphorescence of the Phosphorescent Pigments will remain visible upto few
hours in the darkness. The time period can be extended from 2 to 4 hours and
it depends upon the types of the pigments and intensity of the trapped
energy. The other factors upon which the visibility period will depend are:
- Capacity of our eyes for light adaptation
- Surrounding and distance from the phosphorescence
- Surrounding light
- Types of pigments
- Size of the pigments
How to apply Phosphorescent Pigments
These pigments are mix with water based products
in such a quantity, so that it can fully be used at that time because, these
pigments dry up very quickly when these are mixed with water based products.
Users should use a matter medium in order to not call attention instead of
using any flat medium. Instead of using the present surface on which he/she
is working, any acrylic glazing medium can be chosen. The extraordinary
feature of these Phosphorescent pigments is that these can bring glows in
the color palette in the dark.
Example: For an image having approximate dimension of 12" each and
two glazed spoons into a plastic container.
Put a teaspoon of pigments on a plastic lid or paper lid. First, immerse
the brush into the glaze and then dip into the pigments. The mixture of the
pigments and glaze can be used on the stencil if the user have a stencil.
For mixing the mixture on the stencil, user should follow the circular
motion. Instead of offloading, user should apply the circular motion to
offloading the pigments on to the stencil image. Until the whole image is
not being covered, use this method repeatedly. The definition of the image
will be obtained from the stencil pencil. With many applications, the user
will need to build up the pigments.
If the user doesn't have any stencil then he/she can use a brush size. The
brush size should be according to the image that has to be developed. The
desired glow giving effect of the glow image either will be reduced or
eliminated by the painted details. The user must abide the instructions
while working with these pigments. He/she should avoid from any direct touch
with skin or from inhaling the pigment powder. By using any clear acrylic
product, the entire image can be sealed if it is required acrylic product
will not damage the the glow.
Application methods of phosphorescent Pigments
Phosphorescent pigments have a special binding medium. Therefore, these
pigments are mixed together with inks to made phosphorescent inks. For
phosphorescent printing, the printing that is available is only silk screen
Only transparent or translucent resins are suitable for the use
Phosphorescent pigments and a special binding medium are the components of
phosphorescent paints. What material has to be painted? and what method of
painting has to be used? are the two determinants of selecting binding
mediums. Methods of painting are of different types like spray injection,
machine coating etc. the binding medium should have the quality to increase
the light stability.
