Structural characterization &, optical and electrical properties of LiGaO2 & LiGa5O8 micro-nanoparticles-based photodetectors

Regulating the trap distribution of ZnGa2O4:Cr3+ by Li+/Ga3+ doping for upconversion-like trap energy transfer NIR persistent luminescence

“…The translational motion of the GaO 4 tetrahedron generates a band in the lower wavenumber region. 39,41 The FWHM of XRD patterns and Raman spectrum are demonstrated in Fig. S3,† which can prove the orderliness of samples.…”

Effect of Eu3+ doping on the structural, optical, and photoluminescent properties of LiGa5O8 phosphor

“…This peak is attributed to lithium bonded with oxygen in the octahedral site. 16 Upon fitting the Li 1s spectrum of the 4 mol% Eu 3+ -doped sample (Fig. 9(b)), we observed a spectrum that resolved into two peaks.…”

“…Guan et al 15 synthesized Ni 2+ , Tm 3+ co-doped LiGa 5 O 8 using conventional solid-state synthesis and investigated its up-conversion properties. Wang et al 16 synthesized LiGaO 2 and LiGa 5 O 8 through thermal evaporation, observing two types of emission wavelengths: one in the IR region and the other in the green-yellow region of the electromagnetic spectrum. The generation of IR emission was attributed to the presence of defect levels caused by Li + ions and the 2 S – 2 P 0 transition of Li + activator ions.…”

Ordered LiGa5O8 loaded with redox capable Cu2+, Cr3+ ions to manifest interesting optical, magnetic, and catalytic properties

“…The bands at 133, 185, 272, 422, 510, 654, and 760 cm -1 are observed in the Raman spectrum of LGO. The stretching and bending vibrations of GaO 4 manifest as a band near 655 cm -1 [32]. Band in the lower wavenumber region corresponds to the translational motion of GaO 4 tetrahedra [33].…”
