Effect of pressure and temperature on the lifetime ofCr3+in yttrium aluminum garnet

Luminescence properties of Cr3+:Y3Al5O12 nanocrystals

“…The Cr 3+ ions in YAG crystal are characterized by the intermediate ligand crystal field corresponding to the field strength Dq/Bp2.1 [20]. Such crystal field allows both the spin-allowed 4 T 2g -4 A 2g fluorescence transition and the spinforbidden 2 E g -4 A 2g phosphorescence transition.…”

Pressure-induced changes in the energetic structure of the 3d3 ions in solid matrices

“…High-pressure tuning spectroscopy studies on Cr 3+ -activated materials have clearly demonstrated that pressure is an irreplaceable and powerful tool for quantifying the [15][16][17], for identifying the irresolvable multisite behavior of broadly emitting Cr 3+ systems [6,18], and for characterizing the inhomogeneous distribution of Cr 3+ ions in a disordered crystal [11,19,20], or a glass host [21]. The successful application of Cr 3+ -doped materials stimulated our interests in research of other ions with 3d 3 electronic configuration such as Mn 4+ [22,23].…”

The effect of pressure on luminescence properties of Cr3+ ions in LiSc(WO4)2 crystals—Part I: Pressure dependent emission lineshape

“…Previous high-pressure tuning spectroscopy studies on Cr 3+ -activated materials have clearly demonstrated that pressure is an irreplaceable and powerful tool for quantifying the extent of electronic mixing between the 2 E and 4 T 2 states of the Cr 3+ ion [17][18][19], for identifying the irresolvable multi-site behavior of broadly emitting Cr 3+ systems [20,21], and for characterizing the inhomogeneous distribution of Cr 3+ ions in a disordered crystal or a glass host [22]. Since pressure induces the 4 T 2 -2 E level crossing (at high pressure the broad emission band related to the 4 T 2 -4 A 2 transition is replaced by the sharp lines related to the 2 E-4 A 2 transition) many of the important characteristics of the Cr 3+ emission may be resolved and systematically investigated through high-pressure experimentation.…”
