Stabilization of LiB 3 O 5 crystal surfaces

Abstract

Phase state, chemical composition, and morphology of mechanically polished LiB3O5 surface are considered in comparison with as-grown (1 1 0) crystal face. Strong enriching of near surface layers with carbon is observed. A way to improve the polished LiB3O5 surface characteristics is demonstrated.Optical quality LBO crystals, 100x82x45mm3 in size, were grown by the TSSG method without pulling and rotating4. High pure powders of Li2CO3, B203, and MoO3 were used for flux preparation. As it was determined by X-ray powder

Electronic structure of α-SrB4O7: experiment and theory

“…For this reason, the top surface layer of SBO particles can be doped with Si and Al. It should be pointed out that top surface chemical modification of borate crystals is a well known effect [53,55,56,[63][64][65]. In combination, all these effects may generate different chemical states of O 2− ions and result in the increased FWHM parameter of the O 1s core level.…”

X-ray topography study of LiB3O5crystals grown from molybdate flux

“…The combination of the wide range of transmission, large acceptance angle, moderate nonlinear optical coefficients and relative surface chemical stability allows extensive application of lithium triborate, LiB 3 O 5 (LBO), in high-power nonlinear optical devices [1][2][3][4]. The LBO crystal is characterized by point space group Pna2 1 and the lattice parameters a = 8.446(2) Å, b = 7.380(2) Å and c = 5.147(2) Å.…”
