Rb<sub>7</sub>PbY<sub>2</sub>(B<sub>5</sub>O<sub>10</sub>)<sub>3</sub>: A Noncentrosymmetric Rare-Earth Borate Nonlinear Optical Crystal with [B<sub>5</sub>O<sub>10</sub>] Unit
For ultraviolet (UV) nonlinear optical (NLO) crystals, three fundamental parameters are essential: the absorption edge, the NLO coefficient, and the shortest wavelength for second harmonic generation (SHG) phase matching (PM). In this study, a rare-earth borate, Rb<sub>7</sub>PbY<sub>2</sub>(B<sub>5</sub>O<sub>10</sub>)<sub>3</sub>, was synthesized via chemical cosubstitution using a high-temperature melt method. Rb<sub>7</sub>PbY<sub>2</sub>(B<sub>5</sub>O<sub>10</sub>)<sub>3</sub> has been found to crystallize with a noncentrosymmetric (NCS) space group and has an SHG intensity of 1.3 times KDP and a UV cutoff edge of less than 300 nm. These properties indicate that Rb<sub>7</sub>PbY<sub>2</sub>(B<sub>5</sub>O<sub>10</sub>)<sub>3</sub> exhibits significant potential as an NLO material.
