The advent of watches allows people to calculate and schedule the time accurately, but at night or in other dark places, the time cannot be read at any time, and the time cannot be easily “controlled.” Time is sometimes life, and the result of success or failure is instantaneous, and the opportunity is fleeting. Glow in the dark watches came into being, becoming a bright pearl in the night, illuminating the way forward.
When buying a watch, I usually pay attention to what movement, waterproof performance, brand, and origin of the watch, do you ignore the luminous? Many friends asked me, would the luminous material of the watch harm the body? Let’s introduce the luminous materials of the watch today.
What are the traditional luminous materials?
Traditional luminous materials can be divided into two types: self-luminous and light-storing. The self-luminous glow powder is mostly based on the trace radioactive material carried by itself, which releases rays to excite the fluorescent agent to emit light.
The light-storing luminous powder basically does not contain radioactive substances, as long as it absorbs and stores sufficient intensity of light energy to store the energy. When the surrounding environment is dark, the luminous powder starts to glow. However, the light-storing type itself does not carry ray-excitation materials, so the persistence of afterglow is temporarily inferior to the self-emitting type.
Watches with radioactive elements precipitate with time and have more flavor; modern new-type luminous materials have strong stability and do not change color. Now that the time for multiple-choice questions is up, do you prefer radioactive elements to decay with time and gradually turn into yellow luminous materials, or do you like new luminous materials that can maintain the original luminous effect for a long time?
