Growth and properties of new nonlinear LiKB4O7 single crystals

Acoustooptic and acoustic properties of KLiB4O7 crystals

“…A wide range of their optical transparency, particularly in the ultraviolet region [15][16][17][18][19] (up to 125 nm for 4 7 SrB O [18, 19]), and a high level of optical damage threshold [19,20] make them attractive for optoelectronics. 4 7 KLiB O crystals abbreviated hereafter as KLTB are grown by using isovalent substitution of half of Li atoms by K ones in the initial 2 4 7 Li B O compound [21,22]. At the room temperature KLTB belongs to the acentric point group of symmetry 222 [21,22], the lattice parameters being 8.4915A a = , 11.1415A b = and 12.6558A c = [22].…”

X-ray and thermoluminescence of LiKB4O7 single crystals

“…A very small number of physical properties for LKBO have been studied till today [8][9][10], except the single crystals growth process [5][6][7]. But the luminescence properties of LKBO had been not investigated completely.…”

Low‐temperature change of lattice parameters in LiKB4O7 single crystals

“…Therefore, optically transparent single crystals may be grown from the stoichiometric melting composition [3,4]. However, to date, the LKB4 crystal has been studied insufficiently and some of the results are contradictory.…”

“…2 Experimental Starting LKB4 compounds were prepared by a conventional solid-state reaction technique at T = 980 K. LKB4 single crystals were grown in a platinum crucible by the Czochralski method from the congruent melt in air atmosphere [3]. The single-crystal sample was ground to powder for X-ray diffraction investigations.…”
