Development of a setup for measuring the afterglow scintillating materials

The scintillating materials are essential for the technology developments as they find various applications including high energy physics, security, medical and industries. The main ideal scintillator characteristics include high light yield, fast decay time, high density, high radiation and mechanical hardness and low afterglow. The afterglow is basically defined with the emitted light left after switching off the higher energy radiation. High afterglow not only decreases the light the application output of the scintillator, it has also deterministic effect like the ghost effect in radiography and limits the application of scintillating materials in various devices. The afterglow mainly depends on the scintillation kinetics and defect structure of the materials
