Example Embodiment
[0062] Example 1:
[0063] Add 0.7mmol of tartaric acid and 60mL of deionized water into the reaction vessel and place it in an ultrasonic cleaner for 30 minutes, then add 5.6mmol of vanadium pentoxide to the reaction vessel and stir for 20 minutes, then add 3mL of directing agent 25% ammonia dropwise Stir and react for 50 minutes to obtain a precursor solution. Take 50 mL of the precursor solution and transfer it to a reactor with a 100 mL polytetrafluoroethylene liner. At the same time, put a piece of quartz substrate rinsed with deionized water into the reactor. In the bladder, seal the reaction kettle and let it stand for 5 hours, then put the reaction kettle in an oven and heat it to 180°C for 24 hours and cool it naturally. After opening the autoclave, take out the substrate and rinse it with deionized water once, then rinse once with ethanol, repeat the rinse three times, and dry it at 60°C for 8 hours to obtain (NH) deposited on the quartz substrate. 4 ) 2 V 4 O 9 film.

[0066] Example 2
[0067] Add 0.7mmol of tartaric acid and 70mL of deionized water to the reaction vessel and place it in an ultrasonic cleaner for 30 minutes, then add 5.9mmol of vanadium pentoxide to the reaction vessel and stir for 30 minutes, then add 6mL of directing agent ammonia dropwise and stir. After reacting for 30 minutes, the precursor solution is obtained. Take 60 mL of the precursor solution and transfer it to a 100 mL polytetrafluoroethylene liner reactor. At the same time, put a piece of quartz substrate rinsed with deionized water into the reactor liner. After the reaction kettle is sealed, let it stand for 10 hours, and then put the reaction kettle in an oven to heat to 180°C for 24 hours, and cool naturally. After opening the autoclave, take out the substrate and rinse it with deionized water once, then rinse once with ethanol, repeat the rinse three times, and dry it at 60°C for 10 hours to obtain (NH 4 ) 2 V 4 O 9 film.

[0069] Example 3
[0070] Add 0.73mmol of tartaric acid and 40mL of deionized water to the reaction vessel and place it in an ultrasonic cleaner for 20 minutes, then add 6.2mmol of vanadium pentoxide to the reaction vessel and stir for 25 minutes, then add 7mL of directing agent ammonia dropwise and stir. After reacting for 40 minutes, the precursor solution is obtained. Take 90 mL of the precursor solution and transfer it to a 100 mL polytetrafluoroethylene liner reactor. At the same time, put a piece of quartz substrate rinsed with deionized water into the reactor liner. After the reaction kettle is sealed, it is allowed to stand for 10 hours, and then the reaction kettle is placed in an oven and heated to 200°C for 24 hours and cooled naturally. After opening the autoclave, take out the substrate and rinse it with deionized water once, and then rinse once with ethanol. Repeat the rinse three times and dry it at 60°C for 10 hours to obtain (NH) deposited on the conductive glass...
