Blue or red photoluminescence emission in α-Bi2O3 needles: Effect of synthesis method
(2018-01-01)
Monoclinic bismuth oxide (α-Bi2O3) has attractive optical properties and, therefore, its photoluminescence (PL) behavior has been increasingly explored. Besides this fact, the influence of synthesis methods on PL properties ...
Synthesis of PTSH-modified CeO2 nanoparticles: Effect of the modifier on structure, optical properties, and dispersibility
(2013-06-05)
CeO2 nanoparticles were synthesized by the precipitation method and modified with para-toluene sulfonic acid (PTSH), either in situ or post-synthesis. The presence of PTSH in the samples was confirmed by FTIR. PXRD and ...

Preparation and characterization of new Ni-aluminosilicate catalysts and their performance in the epoxidation of (Z)-cyclooctene
(2007)
This work reports the preparation of two series of Ni-aluminosilicates by the sol–gel and the co-precipitation methods. The main difference between the two processes of synthesis is the pH of the initial mixture, 2 for the ...
