How long do phosphors last?

Phosphors are artificial minerals and most last indefinitely. Some sulphides will decompose in humid conditions. Store these in a dry, airtight box or similar to prevent any loss of performance.

How do I deposit phosphors on my substrate?

Please contact us for advice.

Aren't phosphors dangerous?

Generally, no. Phosphors are sometimes confused with the element phosphorus. White phosphorus is an allotropic form of the element that glows faintly in the dark as it slowly decomposes. The name, phosphorus, means ‘Light Bearer’.

When synthetic materials were made 100 years ago that had luminescent properties, it was decided to give them the generic name ‘phosphors’. In fact, only a small number of phosphors contain phosphorus; and mainly in the form of phosphates.

What are the differences between luminescence, fluorescence and phosphorescence?

Luminescence is the process by which a substance emits light, including UV and infrared, as a result of excitation by an external source of energy. That is, it does not come from the heat energy within the substance. External sources of energy include chemical reactions, electric currents, photons of light and ionising radiation.

Fluorescence is a type of luminescence where a substance continuously emits light of one wavelength while absorbing light of a different wavelength. The emission of light stops very quickly after the excitation ceases.

Phosphorescence is the emission of stored light from earlier absorption. Phosphorescent materials continue to emit light for some time after the excitation ceases.
