Introduction

Rareearthelements(REEs)havebeenwidelyusedasdopantsinvariousmaterials,includingsemiconductors,ceramics,andglasses,duetotheiruniqueelectronicandopticalproperties.Inparticular,REE-dopednanoparticleshaveattractedconsiderableinterestinrecentyearsduetotheirexcellentluminescenceproperties,whichmakethemidealcandidatesforapplicationssuchasluminescentmarkers,bioimaging,andsolid-statelighting(1,2).

TraditionalsynthesismethodsforREE-dopednanoparticlesoftensufferfromseverallimitations,suchaslowproductivity,largeparticlesize,andlowluminescenceefficiency(3).Microreactortechnologyoffersapromisingsolutiontoovercometheselimitationsbyprovidingapreciseandcontrollableenvironmentforthesynthe
