What is the relationship between Phosphorescence and Temperature?
The light discharged by a phosphor, hugely depends upon the temperature. When phosphors are kept at high temperature, then for a short period of time, these phosphorus rapidly discharge light. But, when fully charged phosphors are kept at low temperature, then their light discharging rate gets slower. That is why, whenever it is required to test a matter, whether it is phosphorescent or not, the standard temperature is taken. The standard temperature is 23° C.
