Relationship between Ce3+ 5d1 level, conduction-band bottom, and shallow electron trap level in Gd3Ga5O12:Ce and Gd3Al1Ga4O12:Ce crystals studied via pump-probe absorption spectroscopy

Relationship between Ce3+ 5d1 level, conduction-band bottom, and shallow electron trap level in Gd3Ga5O12:Ce and Gd3Al1Ga4O12:Ce crystals studied via pump-probe absorption spectroscopy

Ce3+-doped compounds are typically the preferred materials for the development of inorganic phosphors for white LEDs, displays, and scintillators. In this study, pump-probe absorption spectroscopy was performed for Gd3Ga5O12:Ce and Gd3Al1Ga4O12:Ce crystals using ultraviolet (UV) and visible (VIS) pu...
