Ultraviolet light is an electromagnetic radiation whose wavelength is shorter than visible light and cannot be directly perceived by the human eye. When ultraviolet rays are irradiated on the white paper, the white paper will absorb the ultraviolet rays and fluoresce. Fluorescence means that after a substance absorbs energy, it emits light with a wavelength longer than the absorbed energy. On white paper, fluorescence converts ultraviolet light into visible light, allowing the human eye to see the presence of light. Therefore, we can only see the effect of light when the ultraviolet light shines on the white paper.
Share some identification features of 254nm and 365nm ultraviolet detection minerals
1. Reaction strength: Different minerals have different reaction strengths to different wavelengths of ultraviolet rays. Some minerals, which fluoresce strongly under 254NM UV light, may not show a noticeable reaction under 365NM UV light. Conversely, other minerals may fluoresce strongly under 365NM UV light.
2. Fluorescent color: Different minerals will emit different colors of fluorescence under different wavelengths of ultraviolet rays. For example, certain minerals fluoresce red or blue under 254NM ultraviolet light and yellow or green under 365NM ultraviolet light. These fluorescent colors can be used to distinguish different minerals.
3. Reaction characteristics: Different minerals will have different reaction characteristics under different wavelengths of ultraviolet rays. For example, certain minerals will show specific streaks, spots or patches when exposed to 254NM UV light, which may not have these characteristics when exposed to 365NM UV light. These response signatures can also be used to distinguish different minerals.
It is important to note that identifying minerals at UV wavelengths is a specialized technique that requires experience and expertise. Different minerals may respond similarly, and the same mineral may respond differently under different conditions. Therefore, when conducting mineral identification, various factors should be considered comprehensively and confirmed in combination with other testing methods.
