How do fluorescent sticks glow?

Glow sticks are a common luminous toy that are widely used in concerts, parties, night activities and other occasions. Its luminescence principle and ingredients have always been a topic of curiosity. This article will combine the hot topics and hot content on the Internet in the past 10 days, introduce the light-emitting principle of fluorescent sticks in detail, and provide structured data for easy understanding.

1. The luminous principle of fluorescent sticks

The luminescence of fluorescent rods is a chemical luminescence phenomenon, the core of which is to release energy through chemical reactions to excite fluorescent substances to emit visible light. The specific process is as follows:

When the glow rod is bent, the inner glass tube breaks and the oxidant mixes with the ester compound, causing a chemical reaction and releasing energy. When the fluorescent dye absorbs this energy, the electrons jump to a higher energy level and then fall back to release the energy in the form of light, creating the fluorescence we see.

2. Color differences of fluorescent sticks

The color of the glow stick depends on the fluorescent dye used. Here are the common colors and their corresponding dyes:

3. Precautions for using fluorescent sticks

Although glow sticks are a safe entertainment product, you still need to pay attention to the following points when using them:

1.avoid breakage: The chemical substances in the fluorescent stick may cause irritation to the skin or eyes. Avoid intentionally damaging the outer casing when using it.

2.Keep away from children: Small parts may pose a choking hazard, so young children should avoid letting them play with light sticks alone.

3.environmental protection: After use, fluorescent sticks should be disposed of properly to avoid random discarding and environmental pollution.

4.Temperature effect: High temperature will accelerate the chemical reaction and shorten the use time of the fluorescent stick; low temperature will slow down the reaction and extend the glow time.

4. Popular fluorescent topics on the Internet in the past 10 days

According to search data from the entire Internet, hot topics related to fluorescence in the past 10 days have mainly focused on the following aspects:

5. The future development of fluorescent sticks

With the development of science and technology, fluorescent stick technology is also constantly innovating. New trends currently on the market include:

1.Rechargeable glow stick: Achieve reusable fluorescent effects through LED technology and reduce the waste of disposable products.

2.Smart light stick: Color changes and flashing modes can be controlled through the mobile APP to enhance the interactive experience.

3.biodegradable materials: Develop more environmentally friendly light stick shells and internal components to reduce the impact on the environment.

4.Multifunctional light stick: Combined with lighting, distress signal and other functions to expand usage scenarios.

Through an in-depth understanding of the light-emitting principle of fluorescent sticks, we can better use and appreciate this magical luminous product, and at the same time, we can also pay attention to its innovative development in the future.
