Embodiment 1
[0039] The invention provides a kind of preparation method of super black material, comprises the following steps:
[0040] (1) Place the quartz plate in alcohol, clean it with ultrasonic waves for 5 minutes, and dry it for later use;
[0041] (2) Copper acetylacetonate (Cu(acac) 2 , Aldrich Chemical Co, 97%;) placed in the quartz boat, stand-by;
[0042] (3) Place the copper acetylacetonate in the quartz boat in the evaporation zone in the tube furnace, raise the temperature to 150°C, and hold the temperature for 120min. The quartz glass plate (40mm×200mm×2mm) for collecting the samples is placed in the tube furnace. In the deposition area, the temperature is raised to 700°C, the holding time is 120min, and then the tube furnace is closed;
[0043] (4) Close all valves, turn on the vacuum pump to pump air, and after confirming that the system is airtight, set the experimental parameters, turn on the heating button, and feed the carrier gas Ar (flow rate: 200ml / min, purity: ...

[0048] (2) Copper acetylacetonate (Cu(acac) 2 , Aldrich Chemical Co, 97%;) placed in the quartz boat, stand-by;
[0049] (3) Copper acetylacetonate in the quartz boat is placed in the evaporation zone in the tube furnace, and the temperature is raised to 150°C. The quartz glass plate (40mm×200mm×2mm) for collecting the samples is placed in the deposition zone of the tube furnace, and the temperature is raised to 150°C. 700°C, the holding time is 120min, and then the tube furnace is closed;
[0050](4) Close all valves, turn on the vacuum pump to pump air, and after confirming that the system is airtight, set the experimental parameters, turn on the heating button, and feed the carrier gas Ar (flow rate: 50ml / min, purity: 99.99%), and keep the...
Embodiment 3
[0053] The invention provides a kind of preparation method of super black material, comprises the following steps:
[0054] (1) Place the quartz plate in alcohol, clean it with ultrasonic waves for 5 minutes, and dry it for later use;
[0055] (2) Copper acetylacetonate (Cu(acac) 2 , Aldrich Chemical Co, 97%;) placed in the quartz boat, stand-by;
[0056] (3) Copper acetylacetonate in the quartz boat is placed in the evaporation zone in the tube furnace, and the temperature is raised to 180°C. The quartz glass plate (40mm×200mm×2mm) for collecting the samples is placed in the deposition zone of the tube furnace, and the temperature is raised to 180°C. 700°C, the holding time is 120min, and then the tube furnace is closed;
[0057] (4) Close all valves, turn on the vacuum pump to pump air, and after confirming that the system is airtight, set the experimental parameters, turn on the heating button, and feed the carrier gas Ar (flow rate: 500ml / min, purity: 99.99%), and mainta...
