Defect Regulation Induced Luminescence Improvement of the Broadband Orange Phosphor Lu₂CaMg₂Si₃O₁₂:Ce³⁺ for WLED

Luminescence, Journal Year: 2025, Volume and Issue: 40(3)

Published: March 1, 2025

ABSTRACT Phosphors for white light emitting diode (WLED) have been attracting the attention of researchers to obtain devices with a high color rendering index (CRI) and low correlated temperature (CCT). Herein, broadband orange phosphor Lu 2 CaMg Si 3 O 12 :Ce 3+ is prepared, vacancy created in lattice regulate structure this phosphor. This can be excited well by blue emit ranging from 500 750 nm. By decreasing content lattice, band gap matrix widened. Besides, emission Ce garnet improved, 1.84 reached maximum all samples. The thermal stability maintains 75.5% at 423 K compared that 298 K. WLED device fabricated via coating mixtures cyan Ca Sc onto chip. shows CRI 87.9 CCT 4167 K, verifying great potential WLED.
