Photochromism is the chemical transformation between two forms of molecules, which have different absorption peaks and are reversible. A smart window is one of its applications that controls the transmittance to minimize inefficient energy flows in buildings. Inorganic photochromic compounds have been attracted interests because of its better durability than organic ones, despite of their insufficient photochromic efficiency. To enhance the photochromic efficiency, an upconversion film which converts visible light into UV light could be attached on the top of the photochromic film as most photochromic films absorb UV light around 290 nm. Pr3+ has been chosen for an activator owing to its proper emission peak (280-400 nm). Y2SiO5:Pr3+ nanoparticles were fabricated via hydrothermal method with size around 100 nm, and they were deposited on polyethylene terephthalate film using finger rubbing method.
