Synthesis and red luminescence of Pr3+-doped CaTiO3 nanophosphor from polymer precursor

Frequency and temperature dependent electrical characteristics of CaTiO3 nano-ceramic prepared by high-energy ball milling

“…Such unique properties give this material much attention, and many investigations regarding its many uses have been carried out in recent  years [5]. Recently, visible photoluminescence properties at room temperature in disordered structurally perovskite titanates (CaTiO 3 ) and highly emissive red-emitting phosphors have been reported in the literature [6][7][8][9][10][11] .…”

Synthesis and luminescence properties of the red phosphor CaZrO3:Eu3+ for white light-emitting diode application

“…The shape of the particles is irregular with an average diameter of about 2 µm, which indicates that these micro crystalline phosphors can result in high luminescent intensities and the particles are fit to be used in fabricating the solid-lighting devices [19,20]. in the host lattices, and the strong excitation at 397 nm is assigned to 7 The luminescence intensity of phosphors is always dependent on the doping concentration. Fig.…”

“…Recently, more investigations have focused on luminescent properties of rare earth ion doped perovskite-type oxides, based on the fact that they were extremely stable and could withstand extreme environmental conditions, which could be an outstanding property for applications [7]. Thus a number of ABO 3 -like compounds with the perovskite structure such as A (A = Ca Sr Ba)TiO 3 [8][9][10][11], SrTiO 3 :Al, Pr [12], CaZrO 3 :Ln (Ln = Pr Tm Eu) [13][14][15] and BaZrO 3 :Eu [16,17] had been studied and showed very interesting luminescent properties.…”

Size-dependence of LaF3:Eu3+nanocrystals on Eu3+photo-luminescence intensity

“…5mmol La(NO 3 ) 3 .6H 2 O (Aldrich, co.) 0.25mmol EuCl 3 .6H 2 O (Kishida Chemical, co.) and cetyltrimethylammonium bromide (CTAB, 99%, from SIGMA) with 0, 0.006, 0.009, 0.015mol/L were dissolved in 150mL deionized water. After mechanical stirring for about 20 min.…”

“…The study of rare-earth nanophosphors is currently an active research field [1][2][3] in modern materials chemistry as these compounds have potential applications in optics, optoelectronics, biological labeling, catalysis fields, etc.. Lanthanum trifluoride LaF 3 [4][5][6] is an ideal host material for various phosphors because this material has very low phonon energy (~350 cm -1 ) [4] and thus the multiphonon relaxation of the excited state of rare-earth ions doped can be minimal. In materials science on nanophosphors, it is known that the size of very fine particles greatly influenced their luminescence properties.…”
