Tunable lanthanide/transition metal ion‐doped novel phosphors for possible application in w‐LEDs: a review
Tóm tắt
Lanthanide‐based phosphors have been extensively investigated for their possible applications in solid‐state lighting technologies especially for white‐light‐emitting diodes. In this review article emphasis has been laid on discussing the recent developments of phosphors for warm white‐light production based on various optical characteristics such as quantum efficiency, thermal stability, short emission decay time, long‐term stability, facile synthesis, and low cost of production. We have tried to cover the essential and latest discoveries of the lanthanide/rare earth‐doped phosphors after 2010. New generations of narrow‐band phosphors have also been included. The optical and material properties of several novel phosphors and their luminescence characteristics have been thoroughly discussed.
