Scintillation and optical properties of cerium (Ce)-doped 20Al(PO 3 ) 3 -80LiF (APLF) glass samples prepared by melt quenching are investigated. The properties of these samples are dependent on the doping concentration, and quenching with high Ce concentration is not observed. A high quantum efficiency of 95% is achieved with 3 mol% Ce and with a decay time of around 40 ns from the allowed 5d-4f transition at 350 nm. This quantum efficiency is high compared to other Ce-doped materials such as Ce:LiCaAlF 6 laser crystals. Ce-doped APLF glass can then be used as illuminators, wavelength converters, and scintillators in the ultraviolet region.

Rare earth cerium doping effects in nonlinear optical materials: potassiumhydrogen phthalate (KHP) and tris(thiourea)zinc(II) sulfate (ZTS)

The influence of Ce(IV) doping on ZTS and KHP crystals over a concentration range from 1 to 10 mol% in the solution during crystallization, which leads to a true concentration range from few ppm to few tens of ppm in the crystals has been investigated. The XRD and FT-IR analyses indicate that the crystal undergoes considerable stress as a result of doping. Incorporation of the Ce(IV) dopant into the crystal lattice was well confirmed by energy dispersive X-ray spectroscopy (EDS) and quantified by inductively coupled plasma (ICP) technique. The high-resolution X-ray diffraction (HRXRD) studies reveal that Ce doping in KHP leads to degradation of crystal quality whereas ZTS can accommodate Ce predominantly at the substitutional sites without any degradation of crystalline perfection. The second harmonic generation (SHG) efficiency is not influenced by Ce doping in the KHP crystals while in ZTS crystals, it is enhanced to a considerable extent correlated with moderately improved crystalline perfection.

“…Later, Ce 3+ -doped materials were also found to be suitable for tunable solidstate lasers in UV region [3]. More recently, LiCaAlF 6 :Ce was also found to be a scintillator [4]. Rare-earth-activated LiAEAlF 6 is also reported to be highly sensitive phosphors for dosimetry of ionizing radiations using thermoluminescence [5,6].…”
