[Explanatory Materials/Video] 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 gradually released, but if it is exposed to light again, it will repeat the phosphorescence process. 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 luminescent materials that are often confused with phosphorescence use the radioactive substance radium, which is currently banned.* "Fluorescence" Objects are recognized by the colors that are reflected and absorbed from the light they receive. Normally, they cannot receive energy beyond the visible light spectrum. 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" Materials reflect the light they receive directly, making them appear bright from the light source even in darkness. If there is a light source, they stand out even from a distance, making them suitable for environments where lights are used in the dark.
