A comprehensive review on metal chalcogenides with three-dimensional frameworks for infrared nonlinear optical applications

Oxychalcogenides as Promising Ultraviolet Nonlinear Optical Candidates: Experimental and Theoretical Studies of AEGeOS2(AE = Sr and Ba)

“…Furthermore, the power LIDT as another significant parameter for NLO materials was evaluated by a single pulse test method at 1064 nm. As far as we know, E g as the main influencing factor of LIDT is in proportion to it, so a large LIDT can be inferred. − As confirmed in Figure b, AEGeOS 2 (AE = Sr and Ba) indeed have a considerable LIDT of 1.16–1.19 times that of the reference KDP at the largest particle size range 150–210 μm. Therefore, AEGeOS 2 (AE = Sr and Ba) have prospects to be promising UV-NLO crystals due to their wide band gap (>4.3 eV), good thermal stability (up to 1100 K), broad transparent window (0.26–12.2 μm), phase-matchability, large SHG response (0.7–1.1 × KDP), and beneficial LIDT (1.2 × KDP).…”

Hg2(SeO3)(SO4): the first sulfate selenite with large birefringence explored from d10transition metal compounds

“…Many new compounds containing d 10 cations, like Hg 2+ and Cd 2+ , with a large birefringence have been reported, such as AgHgPS 4 (0.11 at 2090 nm), 27 LiHgPO 4 (0.068 at 1064 nm), 28 β-Ca 2 CdP 2 (0.2 at 2050 nm), 29 etc. 30–35 To explore new metal sulfate selenites with large birefringence, d 10 -TMs were chosen as the charge-balance cations. Our efforts in d 10 TM–SeO 3 –SO 4 systems result in three new metal sulfate selenites, namely, Hg 2 (SeO 3 )(SO 4 ), La 2 Hg 3 (SeO 3 ) 4 (SO 4 ) 2 (H 2 O) 2 and Ag 2 Cd(Se 2 O 5 )(Se 0.3 S 0.7 O 4 ).…”

Phase matching achieved by isomorphous substitution in IR nonlinear optical material Ba2SnSSi2O7with an undiscovered [SnO4S] functional motif

“…12 Over the past few decades, different synthetic strategies have been made to discover novel NCS chalcogenides with recordhigh d eff . [13][14][15][16][17][18][19][20][21][22][23][24] Unfortunately, most of them suffer from NPM in different pump laser wavelengths, such as CsZrPSe 6 (15 Â AgGaSe 2 ), 25 Rb 3 Ta 2 AsS 11 (15 Â AgGaSe 2 ), 26 K 4 GeP 4 Se 12 (30 Â AgGaSe 2 ), 27 CsBa 3 Ga 5 Se 10 Cl 2 (100 Â AgGaS 2 ), 28 Ba 23 Ga 8 Sb 2 S 38 (22 Â AgGaS 2 ), 29 RbCd 4 In 5 Se 12 (40 Â AgGaS 2 ), 30 and Ba 8 Sn 4 S 15 (10 Â AgGaS 2 ), 31 which weakens greatly their final NLO output efficiency and hinders their further application. In general, PM features can be achieved by adjusting the Dn of an NLO crystal.…”
