The luminescence properties of phosphor materials depend on their morphology; this concept is generally accepted . The luminescence characteristics can be effectively regulated by synthesizing different morphologies of microcrystals . It is believed that reducing the particle size to nanometers leads to a decrease in emission intensity . This is due to the reduction in scale, which results in an increase in surface area . As a result, the enlargement of surface area results in a rise in defects and contaminants on the surface . The emission effectiveness of low-dimensional objects is frequently impeded by the surface quenching phenomenon . By making the energy transfer sites of excited states relax without giving off radiation (non-radiative decay), this effect lowers the emission efficiency. The surface quenching effect necessarily hampers the photoluminescence (PL) properties and is linked to the size-dependent luminescence of particles . However, this phenomenon is just the opposite in ferroelectric materials because the depolarization of these materials at the nanoscale is extremely dependent on the scale or thickness of the nanosheets .
