“…However, we carry out the synthesis in presence of CA rather than adding it late for NP functionalization. We anticipate that carrying out synthesis in presence of CA would reduce particle size since the carboxyl acid groups of CA are expected to attach with higher affinity to the surface of the NPs than the hydroxyl groups of EG/DEG [29]. Finally, we aim to examine the effect of the heavy Gd atom on the phosphorescence of EG and CA.…”

“…Isobe et al reported that Ce 3+ ions can be incorporated into the YAG:Ce nanocrystal by the glycothermal method involving autogeneous pressure at relative low temperature (300 • C). [23][24][25] More recently, Nyman et al 26 obtained YAG:Ce nanocrystals at a reaction temperature of 225 • C with a better quantum yield under a 460 nm excitation wavelength than that reported at 300 • C. [23][24][25] A fundamental aspect to consider is the complexity of working with nanopowders, because of their strong tendency to spontaneously agglomerate due to their large surface area and surface properties. For these reasons, the manipulation of nanopowders in wet conditions is preferred and has demonstrated to allow obtaining coatings with high uniformity.…”

“…Among these phosphors, Ce 3+ -doped yttrium aluminum garnet (YAG), which emits yellow light, has found wide use as a phosphor for white light-emitting diodes (LED). However, investigating the luminescent properties of Ce 3+ -doped compounds is of continued interest for the development of novel phosphors [1][2][3][4][5][6][7][8][9][10][11][12][13][14], particularly Ce 3+ -doped scintillators [1,2,9,14], as the allowed 5d-4f transition has a short lifetime and high quantum efficiency in the 10-40 nm range [1].…”
