Abstract EN
Multiple exponential equations have been successfully fitted to experimental long afterglow decay curve data for some phosphor materials by previous researchers.
The calculated decay constants in such equations are used to assess the phosphorescence characteristics of an object.
This study generates decay constants from experimental test data and from existing literature for comparison.
It shows that the decay constants of an object may not be invariant and that they are dependent on phosphor material, temperature, irradiation intensity, sample thickness, and phosphor density for samples.
In addition, the use of different numbers of exponential components in interpretation leads to different numerical results for decay constants.
The relationship between the calculated decay constants and the afterglow characteristics of an object is studied and discussed in this paper.
The appearance of the luminescence intensity is less correlated to the decay constants than to the time-invariant constants in an equation.
