More particularly, the invention relates to novel compositions (e.g., nanoparticles) and related methods of preparation and use that enable upconverting luminescence with an efficient excitation optimized at about 800 nm. A unique class of cascade sensitized tri-doped UCNPs with a biocompatiable 800 nm excitable property are disclosed herein, for example, tri-doped β-NaYF4:Nd, Yb, Er (Tm)/NaYF4UCNPs, which employ Nd3+ as 800 nm photon sensitizer and Yb3+ as bridging ions, having strong green or blue upconversion emissions without photobleaching."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Compositions and methods for upconverting luminescence with engineered excitation and applications thereof","description":"The invention generally relates to materials and methods for creating and/or utilizing upconverting luminescence.
