The influence of some processing conditions on luminescence of SrAl2O4:Eu2+ nanoparticles produced by combustion method

Combustion synthesis and photoluminescence of Nd3+-doped YPO4 nanocrystals

“…So urea must be added in excess amounts. This phenomenon was also found by Yu et al [15]. As the ratio of urea to Y 3+ is 2.5, the optimum luminescence intensities of the samples can be achieved.…”

Operation by Eu luminescence in CaAl2O4:Eu2+ alloys by Zn substitution

“…With the development of scientific technologies on materials, several chemical synthesis techniques, such as co-precipitation [3], sol-gel [4][5][6], microwave [7], Pechini [8] and combustion [9][10][11] synthesis methods have been applied to prepare rare earth ions activation alkaline earth aluminate and/or its phosphors. All of these methods were conducted in liquid phases so that each component can be accurately controlled and uniformly mixed.…”

Mechanoluminescence & Thermoluminescence of SrAL2O4: EU Nano-Phosphors

“…This method appears to hold promise for the preparation of complex oxide ceramics, such as aluminates [15][16]. The effect of different initiating temperature and mass of urea was reported [17] Mechanoluminescence (ML) is the phenomenon that a solid emits photons when it is fractured or deformed [18]. This phenomenon has been observed in many kinds of solids including ionic crystals, semiconductors, metals, glasses and organic crystals [19][20].…”
