Abstract

Gd_2-xMgTiO₆:xSm³⁺ (x = 0.02–0.12) phosphors were prepared using high-temperature solid-state synthesis. Systematic characterization encompassed phase purity, crystal structure, luminescence properties, and thermal stability. Upon 406 nm excitation, distinct red emission arises from Sm³⁺ ions' ⁴G_5/2→⁶H_j (j = 5/2, 7/2, 9/2, 11/2) transitions. The Gd_1.94MgTiO₆:0.06Sm³⁺ specimen demonstrates exceptional thermal stability, maintaining 80.74 % emission intensity retention at 150 °C compared to ambient measurements. Fabricated LED prototypes combining 405 nm chips with this phosphor yield intense red emission, whose spectral overlap with chlorophyll a/b absorption bands and phytochrome P_R/P_FR profiles suggests applicability in plant growth lighting systems.

用于植物生长照明的新型红光可激发Sm3+掺杂Gd2MgTiO6荧光粉

采用高温固相合成法制备了Gd2-xMgTiO6:xSm3+ (x = 0.02-0.12)荧光粉。系统表征包括相纯度、晶体结构、发光特性和热稳定性。在406 nm激发下，Sm3+离子的4G5/2→6Hj （j = 5/ 2,7 / 2,9 / 2,11 /2）跃迁产生明显的红色辐射。Gd1.94MgTiO6:0.06Sm3+样品表现出优异的热稳定性，与环境测量值相比，在150°C时保持80.74%的发射强度保持。将405nm芯片与该荧光粉结合的LED原型产生强烈的红色发射，其光谱与叶绿素a/b吸收带和光敏色素PR/PFR曲线重叠，表明可用于植物生长照明系统。
