Enhancement of the lighting quality for white light-emitting diodes with CaSc2O4:Ce3+ phosphor

Abstract

For the task of realizing greater progress for the light output in white light-emitting diodes (WLEDs), this study focuses on the luminescence temperature subordination feature of CaSc₂O₄:Ce³⁺ phosphor (abbreviated to CaS for this study). Some other aspects of the phosphor were also included in this piece of paper: Huang-Rhys coupling factor, Stokes shift, triggering power, abatement temperature and especially, abatement behavior in CaSc₂O₄:Ce³⁺. Creating the bluish-green LEDs by the combination of blue InGaN chip and CaSc₂O₄:Ce³⁺ is the primary purpose. CaSc₂O₄:Ce³⁺ appears to be a decent green phosphor that can be used in WLEDs made of blue InGaN chip. Production tasks may be based on our investigation for the task of making desirable WLED devices that meet the production demands.
