Optical properties of Tb and Eu doped cubic YAlO3 phosphors synthesized by sol–gel method

Phase transformation of ZrO2:Tb3+ nanophosphor: Color tunable photoluminescence and photocatalytic activities

“…Normally oxide samples require high calcination temperature to get single pure phase. Table 1 shows Tb 3+ doped different oxide hosts prepared at different calcination temperatures [35][36][37][38][39][40]. In the present investigation, the PXRD patterns of ZrO 2 :Tb 3+ (1-5 mol%) were well indexed to tetragonal phase (JCPDS 81-1544).…”

Technological aspects for Tb3+-doped luminescent sol–gel nanomaterials

“…The sol-gel samples of following compositions were prepared: 31 3 -3.93 Pb(CH 3 COO) 2 )-5.9 CF 3 COOH (SG3) in wt%. It should be noted that the amounts of terbium acetate, lead acetate and trifluoroacetic acid are the same in all synthesized samples.…”

“…One of the most useful methods of obtaining the abovementioned materials is the sol-gel method [5,13,14,16,[21][22][23][27][28][29][30][31][32][33][34][35]. This method is well known as a low-temperature route for preparing high quality luminescent materials with good chemical stability.…”

“…Some of these materials are synthesized by the sol-gel method, e. g. [13,14,16,19,[21][22][23]27,28,[31][32][33][34][35]. To the best of our knowledge only a few reports are available on the spectroscopic properties of Tb 3 þ in silica oxyfluoride sol-gel system, e.g.…”

Luminescence and dielectric properties of c -axis oriented (Bi 1.90 Eu 0.10 )(V 1−z Mo z )O 5.5 ferroelectric thin films

“…Eu 3+ ions have been used as a luminescent probe to investigate distortion of crystal structure of many pure materials, glass or solid solutions, by the change of the site symmetry Eu 3+ ions located [11][12][13]. The red emission (R) centered at 619 nm, corresponding to an electric dipole 5 D 0 -7 F 2 transition, which is hypersensitive to the symmetry of the rare earth ions in the host lattice [14].…”
