【Explanatory Materials and Videos】What are the Differences Between Phosphorescence, Fluorescence, and Reflection?
"Glow-in-the-dark" that shines at night, "fluorescent" that stands out during the day, and "reflective" that reflects light. I will clearly explain each of these properties suitable for disaster prevention along with their uses.
**Explanation** "Phosphorescence" It absorbs light energy from sources such as fluorescent lights, LED lights, and sunlight, and releases it in the dark. In reality, it emits light even in bright places, but it cannot be seen when the surrounding environment is bright. Once it stores light energy, it emits light on its own without needing a power source. The light is released gradually, but if light hits it again, it will repeat the phosphorescence. It is primarily made of rare metals, making it expensive, but since it does not require a power source and incurs no running or maintenance costs, it is effective as a marker in dark places. *Note: The commonly confused "glow-in-the-dark" uses the radioactive material radium, which is currently banned.* "Fluorescence" An object's color is recognized by the light it reflects and absorbs. Normally, it cannot receive energy beyond that of visible light. However, fluorescence converts ultraviolet light, which has stronger energy than visible light, into visible light, making it appear more vivid than regular colors. It is suitable for visibility in daylight or well-lit environments. "Reflection" The material reflects the light it receives directly, appearing bright even in darkness from the light source side. If there is a light source, it stands out even from a distance, making it suitable for environments where lights are used in the dark.
