Embodiment 1
[0031] In this embodiment, the glass substrate 5 is covered with an alloy aerochromic film. The film layer of described alloy aerochromic thin film is made up of the alloy layer of 40nm thickness and the palladium (Pd) layer of 5nm thickness (see Fig. 1), wherein the molar ratio of alloy layer Mg, Ni is 20: 1, passes into hydrogen In the state of (4 V / V%), the transmittance of the film was measured to be 20% with light of wavelength λ=670nm.
Embodiment 2
[0033] In this embodiment, the glass substrate 5 is covered with an alloy aerochromic film. The film layer of described alloy aerochromic thin film is made up of the alloy layer of 40nm thickness and the palladium (Pd) layer of 5nm thickness (see Fig. 1), wherein the molar ratio of alloy layer Mg, Ni is 2.5: 1, passes into hydrogen In the state of (4V / V%), the transmittance of the film was measured to be 46% with light of wavelength λ=670nm.
Embodiment 3
[0035] In this embodiment, the glass substrate 5 is covered with an alloy aerochromic film. The film layer of described alloy aerochromic thin film is made up of the alloy layer of 40nm thickness and the palladium (Pd) layer of 5nm thickness (see Fig. 1), wherein the molar ratio of alloy layer Mg, Ni is 5: 1, passes into hydrogen In the state of (4V / V%), the transmittance of the film was measured to be 72% with light of wavelength λ=670nm. The comparison chart of the transmittance of the film in the high and low hydrogen states in the wavelength range of 340-2500nm is shown in Fig. 2 .
