UV-Filtration Properties of a Quasi-One-Dimensional Photonic Crystal

摘要: Tunable ultraviolet (UV) filters that allow for the transmission of specific UV light wavelengths are highly desired in various scientific applications due to their application versatility and precise control over the spectral range. The significance of such filters may be demonstrated when considering such fields as spectroscopy, photobiology and photomedicine, optoelectronics and nanotechnology, solar research, or photovoltaics, which remains a very active research area nowadays. For example, in spectroscopy, the ability to transmit specific wavelengths of UV allows the study of the unique spectral signatures of different compounds, which in turn enables the identification, quantification, and analysis of substances in fields such as chemistry, biochemistry, and environmental science [1–3]. In the field of photobiology, the effects of UV radiation on living organisms are studied because different wavelengths of UV light have varying biological impacts, ranging from DNA damage to influence on cellular processes. Tunable UV filters facilitate precise manipulation of the UV spectrum incident on biological samples, enabling researchers to investigate the specific effects of different wavelengths on cellular mechanisms, photoreceptors, and photosensitive molecules [4]. In photomedicine, tunable UV filters are crucial for selecting the most appropriate wavelengths for therapeutic applications, such as targeted photodynamic therapy orUV-induced sterilization [5]. In optoelectronic and nanotechnology, certain semiconductor materials, such as gallium nitride (GaN), are widely used in UV LEDs and UV detectors [6]. Tunable filters allow researchers to optimize …
