nanoscale rare earth luminescent materials have come forth a lot of new luminescent phenomena such as the red shift of CTS
the broadening of emission peaks
the increase of quenching concentration
the changes of fluorescent lifetimes and quantum efficiency. Investigating and understanding these materials is not only of academic interest but also of technological importance for advanced phosphor applications. Therefore
in this article
progress on the study of nanoscale rare earth luminescent materials has been reviewed. Firstly
summing up the luminescent characteristic of nanoscale rare earth luminescent particles different from those of bulk materials; secondly
summarizing the preparation and spectrum properties of 1D nanoscale rare earth luminescence materials; thirdly
introducing the patterning of luminescent thin films and assemblies in the mesopore template of 2D nanoscale rare earth luminescence materials; finally
the future development trend for the nanoscale luminescent materials is forecasted. That is to say
in preparation
both nanoscale rare earth luminescent materials with good crystal shape
high brightness
nonaggregating
and narrow particle size distributing and ordered array luminescent devices composed of nanowires
nanotubes
nanorods and so on need to be developed. In fundamental studies
more efforts need to be done on the spectra properties rooted in their surface and interface effects. In applications
the key problems of low luminescent brightness and low stabilities must be resolved.
