Embodiment 1
[0024] Embodiment 1, a method for producing a three-dimensional plasmonic photonic crystal.
[0025] For the device used in this example, see figure 1 (You can also refer to the prior patent application number 201510878651.5), the method for producing a three-dimensional plasmonic photonic crystal includes the following steps:
[0026] a. A vacuum reaction chamber 1 is provided, an air inlet 10 and an air outlet 11 are provided on the wall of the vacuum reaction chamber 1 , and two water electrodes 2 are installed in the vacuum reaction chamber 1 . The water electrode 2 adopts a plexiglass tube sealed with glass baffles 3 on both sides and filled with water, and a built-in copper ring 4 is electrically connected to the plasma generating power supply 5 .
[0027] b. Between the two water electrodes 2, three layers of left, middle and right layers of glass are sequentially stacked and laminated. On the three layers of glass, a discharge gap 9 with a cavity cross-section in an H...
Embodiment 2
[0039] The present embodiment is compared with embodiment 1, and concrete experimental parameter is: the structure of three layers of glass is figure 1 In the structure shown, the thickness of the three layers of glass is 1.4mm. In the discharge gas in the vacuum reaction chamber 1, the volume content of argon accounts for 5% of the total volume of the discharge gas. The pressure of the discharge gas is 0.12 standard atmospheric pressure, the discharge frequency of the plasma generating power supply 5 is 54kHz, and the effective value of the discharge voltage is 2.72kV.
[0040] The pattern photos of the three-dimensional plasmonic photonic crystals in which straight and oblique plasmonic photonic crystals coexist in the discharge gap produced in this embodiment are as follows image 3 shown. image 3 Among them, the plasmonic photonic crystals at the middle horizontal position (corresponding to the single air gap position) and the plasmonic photonic crystals at the upper an...
Embodiment 3
[0042] Compared with Embodiment 2, this embodiment differs in that: the effective value of the discharge voltage of the plasma generating power supply 5 is 2.36 kV.
[0043] The pattern photos of the three-dimensional plasmonic photonic crystals in which straight and oblique plasmonic photonic crystals coexist in the discharge gap produced in this embodiment are as follows Figure 4 shown. Figure 4 The three-dimensional plasmonic photonic crystal shown in image 3 Similar to the three-dimensional plasmonic photonic crystal in .
