Morphology control synthesis and photoluminescence of yttrium orthophosphate microstructures

[Display omitted] •The synthesis technique utterly excludes the usage of any harmful chemicals.•Low pH value and reaction temperature leads to bimodal distribution of the particles.•By tuning the reaction parameters, transform the crystal structure and architectural morphology. A facile, simple route for modifying the structural and morphological architecture of trivalent europium ion doped yttrium orthophosphates through pH tuning is described. SEM analysis confirmed the evolution of different architectural morphology through pH tuning. Additionally, the possible mechanism for the selective control of the phase structure and morphological evolution of YPO4:5 Eu3+ was well ascertained. The results strongly augmented that the control phase transformation from hexagonal to tetragonal structure presented a remarkable change in luminescent properties. This change was rationally evaluated, and the influence of the phase and shape on optical properties was well explored. It hints that we can synthesize multi-functional materials by controlling the shape and structure of yttrium orthophosphates.
