Ba3[Al(PO4)3]: rational design of a promising deep-UV transparent SHG crystal with balanced overall performance originating from the condensation of quartz-type [Al(PO4)4]9− units†
Abstract
A new SHG material, Ba3[Al(PO4)3], has been rationally designed by expanding the anionic condensation design strategy from atom-sharing to anionic-group-sharing. As the first Ba3[B(PO4)3]-type acentric phosphate, Ba3[Al(PO4)3] is characterized by moderate second-order optical nonlinearity, beneficial type I phase-matching behavior, deep-UV transparency and high thermal stability, favourable for practical applications.
