Versatile Persistent Luminescent Oxycarbonates: Morphology Evolution from Nanorods Through Bamboo-Like Nanorods to Nanoparticles

Popis výsledku v původním jazyce

Nanomaterials with persistent luminescence (PLNMs) have emerged as important materials in autofluorescence-free detection for their exceptional ability to temporarily detach the excitation and emission procedure. Although significant advances in materials composition have been made, research of morphology-dependent PLNMs synthesis is still lacking. At its core, further understanding toward the morphology optimization and afterglow enhancement is needed for their future expansion. Herein, we report a two-step synthesis to prepare morphology and afterglow controllable persistent luminescent oxycarbonates (La2O2CO3: Eu3+, Ho3+). In step one, we emphasized a precipitation pretreatment to ensure uniform precursor nanorods. Then, a morphology evolution from nanorods through bamboo-like nanorods to nanoparticles as well as the control of afterglow time can be realized by simply changing posttreatment conditions, such as reaction duration and reaction power. In particular, we highlighted the nanoparticles can be easily produced via cutting the bamboo-like nanorod section by section during the effortless mechanical grinding. In addition, the as-obtained PLNMs exhibit an excellent aqueous stability and remain suspended in adtevak from live mouse and 10% glucose beyond 10 days. The experiment of autofluorescence-free H2O2 detection with La2O2CO3: Eu3+, Ho3+ PLNMs employed as sensing probe demonstrates that these PLNMs present a fresh way of using PLNMs as a new H2O2 detection mode without in situ excitation for real time monitoring of H2O2 and glucose.
