高效稀土上转换纳米晶体合成
Synthesis of efficient rare-earth upconversion nanocrystals
摘要
Abstract
The principal synthesis methods for upconversion nanocrystals(UCNCs)are introduced,and their merits and limitations are evaluated.The co-precipitation technique has high yield and scalability,but necessi-tates subsequent calcination to achieve crystallization,which compromises the control over crystal morpholo-gy.The hydro/solvo-thermal approach yields UCNCs with excellent crystallinity and uniform dimensions.However,it offers limited adjustability in their luminescent properties.The thermal decomposition method al-lows for the production of UCNCs with consistent diameters,but requires the use of pre-synthesized metallic precursors.The seed-mediated high-temperature growth technique and the cation exchange method optimize both the morphology and functionality of the crystals,facilitating the synthesis of UCNCs with homogeneous size distribution and superior optical properties.By optimizing the host material,nano-architectures,and em-ploying simulation-driven synthesis guidelines,these methodologies significantly booster the luminescent effi-ciency of the UCNCs.The optimized UCNCs have substantial potential applications in the fields of biological imaging and disease diagnostics.关键词
