Mechanisms of near-infrared to visible upconversion in CsCdBr3:Ho3+

Crystals of CsCdBr3 doped with x% Ho3+ (x=0.35, 2.25) were synthesized and studied by high-resolution absorption, upconversion luminescence and excitation spectroscopy in the temperature range 295-4 K. The time evolution of the upconversion luminescence, within 1.5 ms of a pulsed excitation, was recorded. Two NIR to VIS upconversion mechanisms were identified. Below 100 K upconversion occurs by energy transfer within Ho3+ pairs. Above 100 K an excited-state absorption is dominant. It occurs whenever the energies of the ground- and excited-state absorption steps coincide. At room temperature this latter process overall is 5 times more efficient than the energy-transfer process.

Systematics and anomalies in rare earth/aluminum bromide vapor complexes: Thermodynamic properties of the vapor complexes LnAl3Br12 from Ln = Sc to Ln = Lu

Systematics and anomalies in the rare earth/aluminum bromide vapor complexes have been investigated by the phase equilibrium-quenching experiments. The measurements suggest that the LnAl3Br12 complexes are the predominant vapor compl

COMPLEXES OF YTTRIUM AND LANTHANIDE BROMIDES WITH 4-N-(2'-HYDROXYBENZYLIDENE)AMINOANTIPYRINEY

Ten new complexes of bromides of yttrium and lanthanides with 4-N-(2'-hydroxybenzylidene)aminoantipyrine (HBAAP) having the formula [Ln(HBAAP)2Br2]Br, where Ln = Y, La, Pr, Nd, Sm, Eu, Gd, Dy, Ho and Er have been prepared and characterized. Molar conductance studies indicate 1:1 electrolytic behaviour for these complexes. Their infrared spectra show that HBAAP acts as a neutral tridentate ligand coordinatin throuhg the carbonyl oxzgen, azomethine nitrogen and phenolic oxygen. Electronic spectra showthe week covalent character in the metal-ligand bond. Thermogravimetric studies indicate that these complexes are stable up to about 170.degree .C and undergo decomposition in two stages forming the respective metal bromides as the final products.
