BaMgAl10O17:Eu blue phosphors with MgO coating and microwave irradiation

Synthesis of Nanosized Luminescent Materials and Their Photoluminescence under VUV Excitation

“…This morphology is different from that of samples synthesized by other methods that result in irregular morphology, such as the solid-state method, 69 oxalate coprecipitation process, 70,71 and microwave irradiation synthesis methods. 72 The advantages of sol-gel method could be responsible for this phenomenon, such as good mixing of starting materials in molecular level, limiting reaction space and relatively low reaction temperature. 73 It has been reported in the systems of ZnO and ZnSiO 4 : Mn that the addition of cetyl-trimethyl-ammonium bromide (CTAB) in sol-gel process could improve their luminescent intensity attributing to the interaction between CTA + and anionic group.…”

Advanced Structured of MgO Thin Film for Bio Applications

“…In addition to advanced methods in which we have electron beam based evaporation [19], ion beam sputtered [20], Atomic layer deposition [21], laser ablation technique [22], successive based ionic layer adsorption as well as reaction method [23], AC plasma display panel [24] and electrodeposition [25]. Additionally, numerous deposition techniques like pulsed laser deposition [26], electro-spinning [27] microwave irradiation [28] have been used to deposit such films. Recently, a plethora of published reports regarding the design and synthesis of MgO thin films containing doping or mixing with other oxides or elements for many applications, specifically to antibacterial applications filed.…”

Atomic Layer Deposition of MgO Nanofilms on BaMgAl10O17:Eu2+ Blue Phosphors

“…One of methods to solve these problems is to passivate the surface of BAM phosphors with oxides. The effectiveness of coating the surface of BAM phosphors with several oxides such as SiO 2 [5,6] and MgO [7,8] by using the sol-gel process has been investigated. However, the use of the solgel process resulted in certain problems such as nonuniform and highly defective coating of the phosphor, which, in turn, resulted in a decrease in the luminescence efficiency, despite excellent passivation.…”
