Thermochromic window and method of fabricating the same

摘要

A thermochromic window, the sunlight transmittance of which is adjustable depending on temperature, and a method of fabricating the same. The thermochromic window includes a substrate, a plurality of nanodots formed on the substrate, and a thermochromic thin film coating the substrate and the nanodots. The thermochromic thin film is made of a thermochromic material. The thickness of the thermochromic thin film disposed on the substrate is smaller than the thickness of the thermochromic thin film disposed on the nanodots.

主权项

1. A thermochromic window comprising:
a substrate; a plurality of nanodots formed on the substrate; and a thermochromic thin film coating the substrate and the nanodots to form a valley portion on the substrate and a peak portion on the nanodots, the thermochromic thin film being made of a thermochromic material, wherein a thickness of the valley portion of the thermochromic thin film extending normal to the substrate is smaller than a thickness of the peak portion of the thermochromic thin film extending normal to the nanodots, and the plurality of nanodots increases visible light transmittance such that the thermochromic window has higher visible light transmittance than when the plurality of nanodots is removed from the thermochromic window.
