Researchers in Michoacan University of San Nicolas de Hidalgo in Mexico designed a new type of illuminating cement called phosphorescent cement that could light pathways or buildings without using electricity.
Led by José Carlos Rubio Ávalos, the team pick the raw materials used in cement, adds them with certain additives and modified its optical properties making it phosphorescent.
Phosphorescent materials work by absorbing energy from radiation, and later, they emit it as light, which can then be seen once it gets dark.
“By using additives, scientists are able to prevent the formation of crystals that occur normally during the production of cement, creating a material with a noncrystalline structure—similar to glass—that allows passage of light inside. Varying the proportion of additives added while manufacturing the cement regulates both its luminescent intensity and color.” told by Scientific American on how it works.
The team asserts that the cement will be able to absorb enough energy to remain illuminated for up to 12 hours even when the day is cloudy. However, they note that its stability should be further studied, and that they also need to investigate how to repair it when it’s damaged.

The same products were manufactured before where in Netherlands there was a bicycle lane inspired by Van Gogh’s Starry Night made with phosphorescent stones. It was developed by Daan Roosegaarde as a tribute to Vincent van Gogh.
