Facile Synthesis of LnPO₄: Tb (Ln = Ce, Gd) Green Emission Phosphors at Specific Temperature (80 or 680°С)

Abstract:

Cerium and gadolinium phosphate micro-meter size phosphors with average diameters of 20-50 μM were prepared. X-Ray Diffraction (XRD) data confirmed the crystalline phases of samples could be formed at different temperature. Scanning electron microscopy (SEM) investigated the morphology and crystalline of the samples, showing that many regular and large pores (100-200 μM) were dispersed within the micro-meter scale composites. We have proved the above crystal growth structures were controllable and predicable based on the current conditions.
