“…The excitation spectrum of the Pr 3+ emission consists of a broad double band stretching from about 225-160 nm, which we assign to the f-d transitions of the Pr 3+ ions. Its spectral position is consistent with the corresponding f-d bands in the excitation spectra reported for other fluoride crystals doped with trivalent praseodymium (Kück et al, 2005).…”

Spectroscopic characteristics of Pr 3+ and Eu 3+ in K 2 Na 2 GdF 7 , K 5 Li 2 GdF 10 and K 3 GdF 6 fluoride matrices are considered. Crystal structures of these compounds have been ascertained based on X-ray measurement on single crystal samples. Energies of lattice vibrations have been derived from IR and Raman spectra. Spectroscopic features of crystals in the VUV region were studied using experimental facilities of the Superlumi station at HASYLAB in Hamburg. High-resolution spectra and decay curves of luminescence in the visible were used to determine the energy levels and excited state relaxation dynamics of luminescent ions. Relevance of energy transfer processes, which feed the 5 D J levels of Eu 3+ and the 3 P 0 level of Pr 3+ , is discussed.

“…The photon-cutting phenomenon is feasible when the 1 S 0 level is located beneath the lowest 5d levels of Pr 3+ . Detailed study of this phenomenon in numerous praseodymium-doped fluoride matrices has been recently reported (Kück et al, 2005).…”

“…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
