Generalized synthesis of 1-D nanoporous aluminates by using a sacrificial template especially evidenced in case of ZnAl2O4:Eu3+ phosphors

Synthesis and photoluminescence of ZnAl2O4:Eu3+ hollow nanophosphors using carbon nanospheres as hard templates

“…2a-c. Apparently, the present synthetic route for preparing ZnAl 2 O 4 :Eu 3+ hollow nanophosphors is different from the surfaceadsorption method, since the precipitation process is not limited the adsorption capacity of the surface [17]. In our laboratory, synthesis of other aluminate nanophosphors with novel hollow structures such as MgAl 2 O 4 :Eu 3+ are in progress via the simple and efficient template method assisted with carbon nanospheres.…”

“…It was found that the crystallinity of ZnAl 2 O 4 nanocrystals obtained using urea as the basic source is much better than that in case of hexamethylenetetramine or hydrazine monohydrate. Besides, we demonstrated a hydrothermal synthetic method to prepare 1-D NH 4 Al(OH) 2 CO 3 nanowires acting as sacrificial templates, which were further converted into 1-D nanoporous ZnAl 2 O 4 :Eu 3+ phosphors under calcining conditions [17].…”

Synthesis, characterization and studies of radiative properties on Eu3+-doped ZnAl2O4

“…Lou and Hao [16] have reported cathodoluminescent properties and CIE chromatic coordinates on films Eu, Tb, Tm doped ZnAl 2 O 4 phosphors. The emission properties of nanostructured Eu doped zinc aluminate spinels were reported by Strek et al [5] and Ma et al [17] Recently, several research groups have devoted significant efforts towards the synthesis and characterization of rare earth doped ZnAl 2 O 4 phosphors in the nano regime. In the present work, Eu 3 þ -doped ZnAl 2 O 4 were synthesized and a detailed PL study was carried out.…”

“…[3,[5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Nevertheless, luminescent properties are greatly dependent on the grain size, leading to attractive properties when the gain size decreases.…”

Structural, Morphological, Optical and Electrical Characterization of Gahnite Ferroan Nano Composite Derived from Fly Ash Silica and ZnO Mixture

“…Aluminum-based spinels depict an intriguing group of oxide ceramics with diverse applications [24]. Among these, gahnite prominently serves as a pigment, in optoelectronics and as a transparent semiconductor, a photo catalyst, and a ceramic material [21][22][23][25][26][27][28][29][30]. An enormous number of applications can be possible by using gahnite as the base material.…”
