Preparation of BaMgAl10O17:Eu2+ phosphor with small particle size by co-precipitation method

Blue and green emissions with high color purity from nanocrystalline Ca2Gd8Si6O26:Ln (Ln = Tm or Er) phosphors

“…In view of this, solid-state reaction method [18] and several wet chemical techniques such as co-precipitation [19], sol-ge1 [10], combustion [20], hydrothermal [17], solvothermal [4] and spraypyrolysis [21] have been explored to prepare the homogeneous phosphor precursor. These wet chemical processing methods offer an intimate mixing of starting materials and hence have shorter diffusion distances between reactants, thus requiring a relatively low temperature for the formation of final products with excellent chemical homogeneity [22].…”

Synthesis of High‐Performance BaMgAl10O17:Eu2+ Phosphor Through a Facile Aqua‐Suspension Method

“…Repeated mechanical mixing is necessary to achieve the narrow particle‐sized distribution, resulting in an irregular particle morphology and surface damage, which is harmful to the photoluminescence properties . This motivated the development of new synthesis methods, such as combustion, co‐precipitation, hydrothermal process, spray pyrolysis, sol‐gel and so on. However, those methods suffer complicated operation procedure, contamination of organic additives, and difficulties in controlling morphology as well as powder agglomeration …”

Reddish orange long afterglow phosphor Ca2SnO4:Sm3+prepared by sol–gel method

“…In recent years, numerous methods have been employed to prepare phosphors, including sol-gel process [17][18][19], chemical precipitation method [20,21], combustion synthesis [22,23], combustion-assisted synthesis method [24,25], sol-gel-combustion process [16], microwave-assistedsol-gel route [26], reverse microemulsion method [27,28], hydrothermal method [29,30], spray pyrolysis method [31,32], template assisted co-deposition method [33], etc. Among them, sol-gel process is an efficient technique for the preparation of phosphors; it has some advantages, such as good mixing of starting materials, relatively low reaction temperature and more homogeneous products [34,35].…”
