“…In our opinion the spectral distribution of this emission reported in [15] is promising for application purposes, namely in the design of quasi-white light sources and possibly all-solid-state yellow laser. Systematic examination of structural peculiarities and of room temperature optical spectra of (Lu x Gd 1-x ) 2 SiO 5 :Sm 3+ single crystals with 0.11 < x < 0.50 has revealed that spectroscopic features of Sm 3+ change markedly when the change of Lu/Gd ratio induces the structural transition of the host [15]. Intentions of the present work are: (i) to understand the effect of structural modification mentioned above and (ii) to get a more detailed knowledge on the emission ability of materials studied.…”

“…In a more recent paper it has been reported that the change of the LGSO symmetry occurs at 0.15 < x < 0.17 [15]. It has been ascertained also that the melting point of LGSO diminishes monotonously with decreasing Lu/Gd ratio and becomes inferiour to 1800 °C when x ≤ 0.2 [15]. Thus, the choice of the LGSO host for luminescent rare earth ions allows to drop advantageously both the crystallization temperature and the cost of chemicals, thereby making practical applications of these systems more favourable.…”

“…Investigation on growth, crystal structure and scintillation characteristics of cerium-doped LGSO host has revealed that LGSO forms crystals belonging to the C2/c space group inherent to LSO for x value above 0.2 and to the P2 1 /c space group inherent to GSO for x value below 0.2 [12][13][14]. In a more recent paper it has been reported that the change of the LGSO symmetry occurs at 0.15 < x < 0.17 [15]. It has been ascertained also that the melting point of LGSO diminishes monotonously with decreasing Lu/Gd ratio and becomes inferiour to 1800 °C when x ≤ 0.2 [15].…”

Single crystals of (Lu x Gd 1-x ) 2 SiO 5 :Sm (0.5 at%) with x = 0.19 (81% Gd3+) and x = 0.11 (89% Gd 3+ ) belonging respectively to the C2/c and P2 1 /c space groups were grown by the Czochralski method under nitrogen atmosphere. Detailed investigation of their spectroscopic properties were performed with the aim of understanding the effect of structural modification on emission characteristics of incorporated Sm 3+ ions with a special attention directed to a laser potential associated with yellow emission line. It was inferred from low temperature optical spectra that almost all emission intensity in the host with C2/c symmetry comes from one of two available Sm 3+ sites, whereas two Sm 3+ sites contribute to emission in the host with P2 1 /c symmetry. Excitation spectra of Sm 3+ emission recorded in the VUV-UV region between 100 nm and 350 nm made it possible to locate the energy of CT transition at about 6.11 eV and to assess the low energy limit for the 4f 5 → 4f 4 5d 1 transitions of Sm 3+ to about 6.81 eV. It implies that in the two systems studied these energies are advantageously high thereby preventing the contribution of intense allowed transitions to an adverse excited state absorption of both blue pump radiation and yellow emission. Experiments of optical amplification of yellow emission were performed employing a pump-and-probe technique in order to verify this implication. It was found that for a LGSO:Sm 3+ crystal having the C2/c symmetry an increase of the pump power density from 20 mJ/cm 2 to 50 mJ/cm 2 at a constant power probe density of 150 μW/cm 2 brings about a positive gain growing from about 0.25 to 2 [cm −1 ]. In the same conditions a maximum gain value of 1 cm −1 was measured for LGSO:Sm 3+ crystal having the P2 1 /c symmetry. It was concluded that the former system is promising for the design of all-solid-state yellow lasers. 85-93 (2012). 9. C. Li, R. Moncorge, J. C. Souriau, C. Borel, and Ch.
