Abstract

EuCa₄O(BO₃)₃ (EuCOB) crystals were grown by the Bridgman method for the first time. The purpose of this work is to evaluate the visible laser application prospect of EuCOB single crystal. The phase structure, thermal properties, and optical properties of EuCOB were studied, and the density of states was calculated by the first principles. The cell parameters of the EuCOB crystal are a = 8.0966 Å, b = 16.0309 Å, c = 3.5670 Å, and β = 101.29°, respectively. The thermal conductivity of the EuCOB crystal is 2.98 W m^–1K^–1, which has a significant advantage in RCOB series crystals. The melting point of EuCOB crystal is 1480 °C. The maximum absorption cross-section of the EuCOB crystal is 1.0123 × 10^–21 cm² (@393 nm), the maximum emission cross-section along the Y direction is 2.644 × 10^–21 cm² (@610 nm), and the fluorescence decay time τ is 1.04 ms. A series of data and analyses prove that the EuCOB crystal is a potential red laser gain material and has great potential in the field of subsequent lasers.

EuCa4O(BO3)3 单晶的生长、结构、光学和热学特性

首次用布里奇曼法生长出了 EuCa4O(BO3)3 (EuCOB) 晶体。这项工作的目的是评估 EuCOB 单晶的可见激光应用前景。研究了 EuCOB 的相结构、热性质和光学性质，并通过第一原理计算了其态密度。EuCOB 晶体的晶胞参数分别为 a = 8.0966 Å、b = 16.0309 Å、c = 3.5670 Å 和 β = 101.29°。EuCOB 晶体的热导率为 2.98 W m-1K-1，在 RCOB 系列晶体中具有明显优势。EuCOB 晶体的熔点为 1480 ℃。EuCOB 晶体的最大吸收截面为 1.0123 × 10-21 cm2（@393 nm），沿 Y 方向的最大发射截面为 2.644 × 10-21 cm2（@610 nm），荧光衰减时间 τ 为 1.04 ms。一系列数据和分析证明，EuCOB 晶体是一种潜在的红色激光增益材料，在后续激光领域具有巨大潜力。
