YbAl3(BO3)4 and YAl3(BO3)4 crystallization from K2Mo3O10-based high-temperature solutions: Phase relationships and solubility diagrams

Crystal growth and optical properties of YAl3(BO3)4 for UV applications

“…YAl 3 (BO 3 ) 4 (YAB) is an old crystal that has been widely studied as a host material for laser applications [6,7]. It is usually grown from the K 2 O-MoO 3 -B 2 O 3 flux system [8,9] and the cut-off wavelength was measured to be about 300 nm. There have been few reports of YAB as a NLO crystal for harmonic generation, though it has a lot of good properties such as large NLO coefficient, moderate birefringence and good physical and chemical stability.…”

Comparative Investigation on the Emission Properties of RAl3(BO3)4 (R = Pr, Eu, Tb, Dy, Tm, Yb) Crystals with the Huntite Structure

“…The RAB and R:YAB crystals (R = Pr, Eu, Tb, Dy, Tm, Yb) were grown from K 2 Mo 3 O 10 -based flux melts in the 1150-900 • C temperature range. The details of the growth procedure are well described in several papers [3,5,13]. The flux growth technique, adopted because the RAB compounds melt incongruently, entails the unavoidable contamination of the crystals by flux components.…”

“…Borate crystals of the huntite family with the general formula RX 3 (BO 3 ) 4 (R = lanthanide ions, X = Al, Ga, Fe, Cr) have been the subject of both fundamental and technologically oriented studies [1,2] for more than fifty years. The ability to grow good optical quality single crystals at relatively low temperatures [3], the insensitivity of the huntite structure to the cation replacement, and the presence of a single lanthanide site with defined local symmetry make these materials very suitable for investigations of the structure of the energy levels and the de-excitation mechanisms of the active ions [4,5]. Furthermore, the combination of favorable chemical and physical characteristics like stability, hardness, high UV transparency, and nonlinear optical properties make them attractive for application in several fields: lasers [6,7], scintillators [8], phosphors [9,10] and so on.…”
