“…1 is composed of distorted GdF 6 and K(1)F 6 octahedra and K(2)F 4 tetrahedra. The GdF 6 and K(1)F 6 octahedra are linked together by apical F(3) fluorine atoms and form chains along c direction. Equatorial F(1) and F(2) fluorine atoms are shared by GdF 6 and K(1)F 6 octahedra in the (a, b) plane.…”

“…Energy separation between the 3 P J levels is comparable to phonon energy available in majority of crystal hosts, therefore, the decay of excited 3 P 2 and 3 P 1 levels is governed by fast nonradiative relaxation, which feeds the 3 P 0 level. It follows from vibrational analysis that the highest energy phonons in K 3 GdF 6 are related to the A 1g vibration at 456 cm −1 and to the T 1u vibration at 370 cm −1 of the GdF 6 3− moiety [13]. Mean energies of the 3 P J multiplets can be inferred from the excitation spectrum of the 3 P 0 emission, shown in Fig.…”

“…Based on results of investigation of numerous fluoride crystals doped with rare earth ions, it has been concluded that singly doped matrices are not able to fulfil the requirements of high conversion efficiency needed in practice [1,2]. Particular attention was directed to praseodymium-doped crystals, in which the 1 S 0 level is located at lower energy than the 5d levels [3][4][5][6][7][8][9][10]. As a result, VUV excitation brings about the cascade emission with a theoretical efficiency exceeding 100%.…”

Single phase, polycrystalline K 3 GdF 6 compound containing 1 at.% of Pr 3+ was prepared and its luminescent properties were investigated in the 10-300 K temperature region. The temperature weakly influences the 3 P 0 emission, whereas the 1 D 2 emission decreases from 520 s at 10 K to 219 s at 290 K due to temperature dependent self-quenching effect. Excitation spectra provide evidence that the energy is transferred from the 5d levels of Pr 3+ to the energy levels belonging to the 4f 7 configuration of Gd 3+ .

“…1 Further, Pr 3+ doped oxides and fluoride materials were useful for red emission applications and the emission processes are explained in the previous studies. [3][4][5][6][7][8][9][10] In such studies, Pr 3+ ions in solids emit more than one visible photon for each incident UV excitation photon. Similarly, the Sm 3+ (4f 5 ) ion is an interesting Ln 3+ ion which emits photo energy with high quantum efficiency from its metastable state 4 G5/2.…”

The present work deals with cadmium zinc phosphate glasses doped with different rare earth ions like Dy 3+ , Pr 3+ and Sm 3+ . Optical absorption, emission, and excitation studies were carried out on these glasses at room temperature. All the corresponding rare earth doped glasses showed strong characteristic absorption bands from their ground states. Emission studies reveal that all these glasses exhibit visible emission for their respective excitation wavelengths. From these studies, it is found that the present host glass is suitable for white light emission as well as red emission. Therefore these Cd-Zn glasses are useful for lighting applications
