ZnSe:Mn/ZnS High Temperature Nanophosphors with Very High Quantum Efficiency for White LEDs

Not Accessible

Your library or personal account may give you access

Abstract

We have synthesized ZnSe:Mn/ZnS doped core/shell nanocrystals with 91% quantum efficiency at the 497 nm emission with 453 nm excitation. Combined with their high temperature stability, this makes them very attractive as nanophosphors for white LEDs.
