Query: Green Fabrication of Lanthanide doped Hydroxide-based Phosphors:
  Y(OH)3:Eu3+ Nanoparticles for White Light Generation   Phosphors serve as color conversion layers to generate white light with
varying optical features including CRI, CCT, and luminous efficacy. However,
they have been produced in harsh synthesis conditions such as high temperature,
high pressure, and/or employing a huge amount of solvents. In this work,
facile, water-based and a rapid method has been proposed to fabricate
lanthanide doped hydroxide-based phosphors. In this sense, submicrometer-sized
Y(OH)3:Eu3+ particles, as red phosphor, were synthesized in water at ambient
conditions in <60 min reaction time. The doping ratio is controlled from 2.5 to
20% in terms of mole. Meanwhile, first principle calculations were also
performed on Y(OH)3:Eu3+ to understand the preferable doping scenario and its
optoelectronic properties. As an application, these fabricated red phosphors
were integrated into PDMS/YAG:Ce3+ composite to generate white light. The
resulting white light showed a remarkable improvement (~24%) for LER, a slight
reduction of CCT (from 3900K to 3600K), and an unchanged CRI (~60) as the
amount of Y(OH)3:Eu3+ increases.
