For small-scale discharge panels of volume-dielectric barrier discharge (V-DBD) and surface-DBD (S-DBD) with an Al2O3-ceramic dielectric layer and a sinusoidal alternating current (AC)-voltage at a frequency of 55 kHz, the plasma and the ozone densities in the discharge area are estimated by analyzing the I-V (current and voltage) characteristics and ozone measuring the concentration in a liter-scale container. With a plasma current in the range of 10–20 mA, the plasma density is np ∼ (1018−1019)m−3 for the V-DBD and np ∼ (1017−1018)m−3 for the S-DBD, irrespective of environmental temperature. However, the ozone density generated on DBD is strongly affected by the electrode temperature and is reduced as the environmental temperature is increased. At an environmental temperature as low as 10 °C, the ozone density generated on the V-DBD is as low as n(O3) ∼ (1017−1018)m−3 with a high electrode temperature of more than 100 °C; on the other hand, the ozone density on the S-DBD is n(O3) ∼ (1019−1020)m−3 with a low electrode temperature of ∼30 °C, which is higher by an order of 102 than the plasma density on the S-DBD plasma panel.

具有大气介质阻挡放电的臭氧发生面板

对于体积介质阻挡放电 (V-DBD) 和表面 DBD (S-DBD) 的小型放电面板，具有 Al2O3 陶瓷介电层和频率为 55 kHz 的正弦交流 (AC) 电压，通过分析 IV（电流和电压）特性和测量升级容器中的臭氧浓度来估计放电区域中的等离子体和臭氧密度。当等离子体电流在 10-20 mA 范围内时，V-DBD 的等离子体密度为 np ∼ (1018−1019)m−3，S-DBD 的等离子体密度为 np ∼ (1017−1018)m−3，无论环境温度。然而，DBD 上产生的臭氧密度受电极温度的影响很大，并随着环境温度的升高而降低。在低至 10 °C 的环境温度下，V-DBD上产生的臭氧密度低至n(O3)∼(1017-1018)m-3，电极温度高达100℃以上；另一方面，S-DBD 上的臭氧密度为 n(O3) ∼ (1019−1020)m−3，电极温度低约 30 °C，比等离子体密度高 102 个数量级在 S-DBD 等离子面板上。
