The paper presents an experimental and theoretical study of the radiative emission in the pure krypton lamp excited by dielectric barrier discharge. Parametric studies were made in the aim to observe the influence of the applied voltage, the gas pressure and the frequency on the radiation intensity emission from visible to infrared range. Stable dielectric barrier discharges were achieved between two identical insulated electrodes separated by 2 mm gap containing pure krypton at pressure from 129 to 460 mbar. The discharge was powered with a sinusoidal supply at frequencies from 10 to 50 kHz. Electrical characteristics of the DBD were studied. A spectroscopic and kinetic analysis of a pure krypton dielectric barrier discharge is reported here. The discharge emits radiations in UV, visible and IR range. In order to understand the emission process a theoretical interpretation of the results is given in the IR range by describing the chemical properties of the lamp. IR emission and a detailed study of kinetics allow to follow the population of metastable excited states of Krypton in (Kr*(3P0,2)). This population is indirectly responsible for UV emission.

氪气灯的可见红外辐射发射：实验和理论解释

本文介绍了由介质阻挡放电激发的纯氪灯辐射发射的实验和理论研究。进行参数研究的目的是观察施加的电压、气压和频率对从可见光到红外范围的辐射强度发射的影响。在 129 至 460 毫巴的压力下，在两个相同的绝缘电极之间实现了稳定的介电阻挡放电，该电极由 2 毫米间隙包含纯氪气。放电由频率为 10 至 50 kHz 的正弦电源供电。研究了 DBD 的电气特性。此处报告了纯氪介质阻挡放电的光谱和动力学分析。放电会发出紫外线、可见光和红外线范围的辐射。为了理解发射过程，通过描述灯的化学特性，在 IR 范围内给出了结果的理论解释。红外发射和动力学的详细研究允许跟踪 (Kr*(3P0,2)) 中氪的亚稳态激发态群体。这个群体间接负责紫外线的发射。
