What is the reason of Persistent Glowness of Platinum metal after removing it from the flame ?

The persistence glow of platinum metal is caused by a phenomenon known as phosphorescence, which is the emission of light by a substance after it has been exposed to radiation or heat.
The duration of the glow depends on various factors such as the intensity of the heat, the purity of the platinum metal, and the environment it is exposed to. Generally, the glow can last anywhere from a few seconds to several minutes.
No, platinum is not the only metal that exhibits this phenomenon. Other metals such as zinc, copper, and silver can also retain their glow after being heated. However, platinum is known to have one of the longest persistence glow durations.
Yes, the intensity and duration of the persistence glow of platinum metal can be controlled by adjusting the temperature and the duration of the heating process. The purity of the platinum metal also plays a role in the persistence glow.
The persistence glow of platinum metal has various practical applications, such as in glow-in-the-dark paints and coatings, security features in banknotes, and in industrial processes that require temperature monitoring. It is also used in scientific research and as a visual indicator in some medical devices.
