Solution Phase Synthesis and Photoluminescent Properties of Nanocrystal LaPO[sub 4]:Eu[sup 3+]

Additional of polyethylene glycol on the preparation of LaPO[sub 4]:Eu[sup 3+] phosphor

“…LaPO 4 may form hexagonal and monoclinic structur synthsized by specific method [6]. In order to produce LaPO 4 with high crystinity, various method with high temperatur have been applied such as sol-gel [5], hydrothermal [6][7], other solution phase method [8] etc.…”

Challenging and development of phosphors for lighting applications

“…[49][50][51][52][53][54] Phosphors are synthesized by various methods such as solid state, solution phase and aerosol phase. Several modification on the phosphors synthesis are sol-gel derived flux assisted, hydrolysis and oxidation method, molten salt synthesis, co-precipitation method, spark plasma sintering, high temperature ball milling, hydrothermal, solvothermal co-precipitation, microwave non-hydrolytic sol-gel, self-assemblies, flame-assisted spray pyrolysis and pulse combustion spray pyrolysis [9,[31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48]. Generally, spray pyrolysis method provide high quality phosphors, however the disadvantage is low production rate.…”

“…Generally, these properties could be improved by better crystallization and purifying materials. Current challenges on phosphors research to obtain desired phosphors for lighting application is briefly reviewed in Table 1 respectively on luminescent features and high quantum efficiency [2][3][4][5][6][7], reduced of RE usage for host phosphor [8][9][10][11][12][13][14][15][16][17], morphology and size [18][19][20][21][22][23][24][25][26][27][28][29][30], preparation/synthesis methods [9,[31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48], and new phosphors …”

Synthesis and characterization of ZnO:Ca2+ prepared by simple solution method

“…In order to avoid the utilization, in this paper, the synthesis of ZnO:Ca 2+ samples was investigated via simple solution method. In this method, the particles were prepared without adjustment of pressure and the reaction continued under air [21]. o C to evaporate most water in gel phase.…”

“…Interestingly doping of Ca 2+ shows no additional peaks, which confirms no additional impurity phase formation. The crystallite size in the sample is estimated using the Debye-Scherrer's equation as follows [21]:…”
