Holeburning in rare earth doped nanoparticles of MgS

Optical properties and Judd–Ofelt parameters of Dy3+ doped K2GdF5 single crystal

“…The rare earths (RE) doped glasses provide basically scientific information, such as energy level structure, radiative properties, stimulated emission cross-sections, etc. These information help to develop new optical materials and improve the existing devices like lasers, light converters, sensors, high density memories, and optical fibers and amplifiers [1][2][3][4][5].…”

UV, Blue, Green, Yellow, Red, and Small: Newest Developments on Eu2+-Doped Nanophosphors

“…The same authors extended their work and investigated a possible influence of the particle size on the emission wavelength of ZnS:Eu 2+ nanoparticles. 219,312 Besides ZnS:Eu 2+ , 218−225 also nanosized CaS:Eu 2+ , 11,211 SrS:Eu 2+ , 215 MgS:Eu 2+ , 216,217 GdS:Eu 2+ , 227 CaGa 2 S 4 :Eu 2+ , 230 BaAl 2 S 4 :Eu 2+ , 231 and PbS:Eu 2+226 have been reported in the literature. Lead sulfide nanocrystals doped with divalent europium, for example, were synthesized by the thermolysis of mixed precursors like [Pb(ddtc) 2 phen] and [Eu(ddtc) 2 phen] (ddtc = diethyldithiocarbamate, phen = 1,10-phenanthroline).…”

Correlation between inhomogeneous width and crystallite size: 2E →4A2 luminescence of Co(II) in nanocrystalline ZnAl2O4/Co(II)

“…5 D 0 transition of Eu 2 O 3 nanoparticles, which is a strongly weakened temperature dependence in comparison with the well established $T 7 dependence for bulk samples [7][8][9]. Another interesting example, are the results reported by Hasan et al regarding, hole-burning properties of Eu 3+ doped MgS and CaS nanocrystallites [10,11]. Nanomaterials are often prepared by rapid synthetic methods such as co-precipitation or combustion reactions.…”
