Synthesis of BaAl12O19:Mn2+ nanophosphors by a reverse microemulsion method and its photoluminescence properties under VUV excitation

New Trends on the Synthesis of Inorganic Nanoparticles Using Microemulsions as Confined Reaction Media

“…As for catalytic activity, which was evaluated in the NO reduction by CO, the spinels synthesized in w/o microemulsions was slightly superior. Similar characteristic size was obtained by Wang et al (Wang Y. et al, 2007) (Xu et al, 2007), tungsten oxide (WO 3 ) nanoparticles (Asim et al, 2007), and rutile TiO 2 nanoparticles (Keswani et al, 2010). In the last example, it is remarkable that the rutile phase was obtained at room temperature, without the need for thermal treatment, hence the size of the rutile nanocrystals remained as small as 4 nm.…”

Mn2+ activated MgSrAl10O17 green-emitting phosphor—A luminescence and EPR study

“…The b-alumina of interest in the present study is SAM. In recent years, several research groups have devoted significant efforts towards the synthesis and characterization of various Mn 2+ -doped host materials [14][15][16][17][18] novel combustion synthesis method and evaluated its luminescence properties [19].…”

Synthesis and Vacuum Ultraviolet Spectral Properties of Nano-scaled Phosphors

“…Table 1 shows the ratio of emission intensity and the color coordinates of the tri-color nano-phosphor compared with commercial phosphor. The emission intensity of nano-scaled YBO 3 …”

“…The representative tricolor commercial phosphors for PDP were (Y, Gd)BO 3 [2] . Recently, many researchers have focused on the preparation and luminescent properties of nano-phosphors because of their small size effect, surface effect, and the quantum size effect, which made them promising to present different optical and electrical properties compared with bulk phosphors [3] . Besides, to meet the requirement of the PDP manufacture procedure, nano-phosphors were convenient to brush the panel and they could get higher resolution to make the pictures more vivid.…”

“…In this work, the nano-scaled YBO 3 2 and Mn(CH 3 COO) 2 . After being stirred for half an hour, the mixed solution was transferred into the Teflon reaction vessel in the autoclave and heated at different temperature for 2 h. After cooling down to room temperature naturally, the resultant products were collected by filtration, followed by washing and drying.…”
