Growth, Structure, Optical, and Thermal Properties of EuCa4O(BO3)3 Single Crystals
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.
期刊介绍：
The aim of Crystal Growth & Design is to stimulate crossfertilization of knowledge among scientists and engineers working in the fields of crystal growth, crystal engineering, and the industrial application of crystalline materials.
Crystal Growth & Design publishes theoretical and experimental studies of the physical, chemical, and biological phenomena and processes related to the design, growth, and application of crystalline materials. Synergistic approaches originating from different disciplines and technologies and integrating the fields of crystal growth, crystal engineering, intermolecular interactions, and industrial application are encouraged.
