Effect of morphology and temperature treatment control on the photocatalytic and photoluminescence properties of SrWO
Autor: Nadine, Dirany, Abdelali, Hallaoui, Jean Christophe, Valmalette, Madjid, Arab
Publikováno v: Photochemicalphotobiological sciences : Official journal of the European Photochemistry Association and the European Society for Photobiology. 19(2)
This work reports the combined effect of the morphology and crystallization degree of the strontium tungstate (SrWO4) scheelite structure on its photocatalytic and photoluminescence properties. The difference in the precursor ratio leads to two morph
