Abstract

A facile and controllable ethanol/water aided hydrothermal process was developed to prepare the NaCaSiO₃OH:Tb³⁺/Eu³⁺ phosphor. The morphologies were in situ constructed with the phase transformation from NaCaSiO₃OH to Na₂Ca₂Si₂O₇, and the intrinsic crystal structural transformation mechanism and the dependence of their photoluminescence tuning on the Tb³⁺/Eu³⁺ ratio have been discussed.
