Time-resolved spectroscopy of 5d-4f transitions in Pr doped alkali-earth fluorides
نویسنده
چکیده
We measured time-resolved spectra and emission decay times under pulsed X-ray and synchrotron excitation in alkali-earth fluorides doped with Pr ions. Two fast decay components were found in the emission spectra of BaF2-Pr 3+ and SrF2-Pr 3+ . These were 4 ns and 21 ns in BaF2-Pr 3+ and 8 and 24 ns in SrF2-Pr . The intensity of the faster components 4 ns and 8 ns depended on concentration of Pr. Thus, the presence of aggregates might be the cause of such faster components.

Time-resolved luminescent VUV-spectroscopy of pure and doped by rare earth ions crystals of strontium fluoride
The spectroscopic properties SrF2–Eu(1%), SrF2–Er(1%) and nominal pure SrF2 crystals have been studied using time-resolved vacuum ultraviolet (VUV) spectroscopy under pulsed synchrotron radiation excitation. The 4f24f 5d (f–d) and 4f24f (f f) excitation spectra and emission spectra (with and without of time resolution) have been investigated in the wide energy region at 8 and 295K. Moreover, th...

Herein we present a Ligand Field Density Functional Theory (LFDFT) based methodology for the analysis of the 4f(n)→ 4f(n-1)5d(1) transitions in rare earth compounds and apply it for the characterization of the 4f(2)→ 4f(1)5d(1) transitions in the quantum cutter Cs2KYF6:Pr(3+) with the elpasolite structure type. The methodological advances are relevant for the analysis and prospection of materia...
متن کاملOptical detection of a single rare-earth ion in a crystal
Rare-earth-doped laser materials show strong prospects for quantum information storage and processing, as well as for biological imaging, due to their high-Q 4f↔4f optical transitions. However, the inability to optically detect single rare-earth dopants has prevented these materials from reaching their full potential. Here we detect a single photostable Pr(3+) ion in yttrium aluminium garnet na...
متن کاملDirect calculation of 4f(3)-4f(3) transition intensities in Nd(3+)-doped YPO(4) system involving explicit effects of 4f(2)5d configuration.
The effects of the 4f(2)5d configuration on the intraconfigurational [Formula: see text] electric dipole transitions of Nd(3+) doped YPO(4) are taken into account by a 'direct' calculation. A simple model is applied to analyze the opposite-parity 4f(2)5d configuration admixing into 4f(3) transitional states. The matrix elements of the odd-rank crystal-field interaction and the interconfiguratio...
