Are you looking for a phosphorescent material?<\/h2>\n

OliKrom<\/a> has acquired a unique expertise in the field of phosphorescent materials. Our team masters the most advanced concepts in materials science, <\/strong>chemistry and photochemistry science to design and produce glow powder, ink and paint with high luminous intensity and a varied color palette.<\/p>\n

 <\/p>\n

What is phosphorescence ?<\/h3>\n

A phosphorescent material has the ability to store light and restore it in the dark with high luminous intensity.<\/strong><\/p>\n

It is important to distinguish fluorescence which stops as soon as the illumination stops, from phosphorescence which persists. Fluorescence and phosphorescence are two forms of photoluminescence<\/strong>, that is to say presence of light following an absorption of light.<\/p>\n

Phosphorescence is a process of de-excitation between two states of different multiplicity (between the excited state and the ground state) which is not allowed by the quantum model, but which is made possible by the spin-orbit coupling. The transition is consequently slow to take place. In molecular chemistry, the phosphorescence (glow property) process is generally encountered during the relaxation between an excited state T1<\/sub> (triplet state) and the ground state S=0 (singlet state), involving a change of multiplicity.<\/p>\n<\/div>\n<\/div><\/div><\/div><\/div>

The main difficulties observed to obtain a phosphorescent material<\/h2>\n

Stabilize the glow property<\/h3>\n

Today, there is a wide variety of commercial glow pigments, which are essentially green or blue. It is therefore easy to obtain a phosphorescent material. The mixture of a commercial glow pigment in an ink and\/or paint allows to obtain easily a phosphorescent solution.<\/p>\n

The difficulty is if you wish a strong glow intensity in the dark with a stability of the property throughout the production, with a recurrence. By experience, we know that phosphorescent materials are extremely sensitive to shear forces<\/strong>, that an uncontrolled addition of an additive, a dye, a glow pigmentary charge can irremediably reduce the luminous intensity in the dark from several hours to a few minutes.<\/p>\n

Controlling color of a glow powder and pigment<\/h3>\n

Another major challenge is to achieve color control by day and night. Our teams use photochemical cascade to optimize :<\/p>\n
