Abstract

The invention relates to a coating of glass with thermochromic vanadium dioxide. The coloration of the vanadium dioxide is shifted from bronze to neutral (colorless) by a doping with alkaline earth metals, for example Ca, Sr and Br. The thermochromic effect is maintained at the same time.
