Experiments with the so called phosphorescence: Persistent luminescence as thermoluminescence at ambient temperature
Light-excited luminescence with very slow decay (used often in safety signs and instrument dials) is incorrectly called phosphorescence. In reality, it is persistent luminescence with lifetime in the order of minutes and ev...
