Over the last decade, many researchers have explored the use of nanoparticles in the construction industry to produce cement-based materials with superior properties.
Adding metal oxide nanoparticles to cement reduces its permeability to ions, increasing its strength and durability (Al-Rifaie & Ahmed, 2016).

Upconverting nanoparticles (UCNPs) are nanoscale particles (diameter 1–100 nm) that exhibit photon upconversion. In photon upconversion, two or more incident photons of relatively low energy are absorbed and converted into one emitted photon with higher energy.
