Organic-inorganic hybrid phosphors doped with lanthanides are gaining widespread attention of researchers due to their significant contribution in display devices and lighting technologies. The fundamental principle governing this approach is based on the suitable design of the precursor host.It is well known that optical properties of nano phosphor become size dependent as structure of the atom is altered by continuous electronic bands to quantized electronic levels. Consequently, due to large surface area, defects are generated which act as non-radiative pathways to the excited electrons and...
