研究目的

To explore a beryllium-free KBBF family member, Zn2BO3(OH), that features the same topological layer with KBBF by replacing [BeO3F]5? with [ZnO3(OH)]5? and exhibits excellent UV performances, aiming to achieve a balance between beneficial layered structure and layer tendency.

研究成果

Zn2BO3(OH) was successfully synthesized as a beryllium-free KBBF family member, exhibiting a SHG response of about 1.5 × KDP@1064 nm with a UV cutoff edge of 204 nm and a birefringence of 0.067 in the visible region. It shows better growth habits than KBBF due to the removal of interlayer cations, achieving a balance between beneficial layered structure and layer tendency. The method proposed for assessing the growth habit of layered-structural crystals from the perspective of thermodynamics can be a reliable approach.

研究不足

The study focuses on the synthesis and characterization of Zn2BO3(OH) and its comparison with KBBF. The practical application and scalability of Zn2BO3(OH) in optoelectronic devices are not explored.
