We are happy to announce that significant progress has been recently accomplished and four different methods for preparation of phosphors based on phosphate and vanadate host were developed and optimized: high temperature solid-state, co-precipitation, reverse micelle and colloidal route.
Samples with particles of different morphology and size with satisfactory luminescent intensity were obtained. At this moment, some of them incorporated in silica waveguides could find potential
pplication for enhancement of 1.3 μm photoluminescence.
The work investigating luminescent lanthanum nanoparticles was presented at international conference ‘’Spectral shaping for biomedical and energy applications’’, SHIFT 2017, 13-17 November, Tenerife, Spain.
The article, with detailed study of nanoparticle’s size effect on structural and optical properties of doped lanthanum and europium phosphate has been accepted for publication, which can be found online. https://doi.org/10.1016/j.jlumin.2017.12.002 Also, very proud to report that a joint manuscript between our team and researchers from Italy, Vietnam, Poland and Serbia studying phosphors based on vanadate host has been submitted and accepted for publication.
We will continue our work, hopefully acquiring materials with improved performances, and attractive practical applications.
