Fluorescence and phosphorescence describe different light-emitting behaviors in materials. Understanding the distinction helps explain Sassi di Luce: the surface absorbs light and gradually releases it after exposure ends.<\/p>\n

When emission follows the source<\/h2>\n

In fluorescence<\/a>, emission stops very quickly after the exciting light is removed. You may recognize this in materials viewed under UV light: they appear bright during exposure, but this does not mean they will continue to emit in darkness.<\/p>\n

Light that continues after dark<\/h2>\n

Persistent luminescent materials release energy after exposure ends. Intensity changes over time: the effect is more visible initially, then fades. In everyday language, this behavior is often called phosphorescence<\/a>. It makes a glowing detail possible without a dedicated electrical supply to the material.<\/p>\n

From terminology to the experience of a space<\/h2>\n

Sassi di Luce brings light and materials together within the paver surface. Observe the product after exposure and consider its intended setting. Intense nearby artificial light can make emission less visible: atmosphere also depends on what surrounds the paving.<\/p>\n

Fluorescence and phosphorescence: frequently asked questions<\/h2>\n

Are fluorescence and phosphorescence the same?<\/h3>\n

No. Fluorescence follows the source and stops quickly when it is removed. Persistent emission can continue after exposure. This difference in timing distinguishes the two behaviors.<\/p>\n

What does photoluminescence mean?<\/h3>\n

It is a general term for light emission following light absorption. The term alone does not establish the duration, intensity or performance of a particular paving product.<\/p>\n

Does a UV lamp demonstrate the nighttime effect?<\/h3>\n

It shows a response during exposure, but does not by itself describe what happens afterward. View the sample after removing the source, in a setting suitable for comparison.<\/p>\n
