摘要

The possibility of trichromatic colouration of glass was investigated by extending staining, which is a conventional glass colouring technique, using soda lime silica glass as a substrate. Silver and sodium nitrates or copper and sodium sulphates mixed aqueous solutions containing polyethylene glycol were applied on the glass substrates. After the solutions were dried at room temperature, a two-step heat treatment process was performed for the substrates at various temperatures. During the first heat treatments, silver or copper ions were incorporated into the glass surfaces. Subsequently, the second heat treatments converted the silver and copper ions into species colouring the substrates. By applying 0.001 to 0.05 M AgNO3 solutions, the substrate turned bright yellow after the second heat treatment in Ar/H-2(3%) reduced atmosphere. On the other hand, by applying 0.46 M CuSO4 and 0.56 M Na2SO4 mixed solution, the substrate turned reddish after the second heat treatment in Ar/H-2 (3%) atmosphere but bluish after the second heat treatment in ambient or O-2 atmosphere. The yellow colour was due to the absorption assigned to the surface plasmon resonance of Ag nanoparticles while the reddish and bluish colours were ascribed to the absorption of Cu2O and Cu metal nanoparticles and d d transition of the Cu2+ ions, respectively. An adequate procedure for applying the solutions and the heat treatments could impart these three colours to the same glass substrate. The CIE chromaticity coordinates were estimated. The coordinates of the yellow were located in the yellow region in the CIE diagram while those of the reddish and bluish colours were near the white region. We obtained three colours near or similar to the trichromatic colours, although the tuning of the colours is still necessary, particularly for the red and blue.
