“…The AD is an analogue of cation isoelectronic impurities and significantly contributes to the intrinsic UV luminescence of single crystals of garnet compounds [6]. The intrinsic luminescence of Ga-garnets, in particular the YGG and LLGG SC, has been recently studied in the papers [6][7][8] by conventional spectroscopic methods. It has been found that intrinsic luminescence of SC of these garnets is represented by broad complex bands in the UV spectral range which are a superposition of several components.…”

a b s t r a c tThe nature of intrinsic luminescence of Y 3 Ga 5 O 12 (YGG) and (LaLu) 3 Lu 2 Ga 3 O 12 (LLGG) single crystals grown from a melt was determined. In the case of a YGG single crystal containing Y Ga antisite defects with a concentration of 0.25-0.275 at.% the intrinsic luminescence was considered as a superposition of luminescence of self-trapped excitons (STE), luminescence of excitons localized near antisite defects (LE(AD) centers) and luminescence caused by a recombination of an electron with a hole captured at Y Ga antisite defects. Due to a large (2-3%) concentration of Lu La antisite defects in LLGG single crystals the intrinsic luminescence was a superposition mainly of the LE(AD) center emission and the recombination luminescence of Lu La antisite defects. The energy structure of the mentioned centers in YGG and LGGG hosts was determined from the excitation spectra of their luminescence under excitation by synchrotron radiation in the range of the fundamental absorption edge of these garnets.

“…It has been found that intrinsic luminescence of SC of these garnets is represented by broad complex bands in the UV spectral range which are a superposition of several components. The position and intensity of these components depend on the AD concentrations and temperature of measurements [6][7][8].…”
