The fluorescence of Cr3+ ions doped insulating crystals was studied under the laser excitation within the one-phonon vibronic sidebands of zero-phonon 4A2 - 2E transitions. The phonon-assisted anti-Stokes fluorescence spectra were observed at ambient

Fine-tuning of the Cr3+ zero-phonon R1-line fluorescence (2E-4A2) has recently been achieved by varying the composition of Cr-doped solid solution garnets. Chemical substitutions of Y3+ with Lu3+ and Tb3+ produce R1-line shifts and multiplets that ca

The 2E - 4A2 fluorescence spectra of probe Cr3+ centers in MgO nanolayers of different thickness deposited on Al2O3 and GaN substrates were studied. The films were produced by laser molecular beam epitaxy (LMBE). The spectra revealed the strong inhom

The fluorescence of Cr3+ ions doped insulating crystals was studied under the excitation in the long-wavelength tail of the absorption spectrum (“laser cooling regime”). The 4T2 - 4A2 and 2E - 4A2 fluorescence spectra with a dominant anti-Stokes
