A simple method for the synthesis of fluorescent zinc chalcogenide (ZnO, ZnS and ZnSe) nanoparticles directly in the transparent PMMA and PS polymer matrices were reported. Highly dispersed small spherical ZnO nanoparticles (3-5 nm) was obtained by hydrothermal reaction of PMMA/PS-Zn(acac)2H2O in toluene. ZnS and ZnSe nanoparticles were prepared by heterogeneous stirring of PMMA/PS-Zn(acac)2H2O in toluene with aqueous solution of thiourea or NaHSe. Interestingly, ZnO and ZnS-PMMA thin film showed strong fluorescence quenching upon exposure to ammonia.
报道了一种直接在透明聚甲基丙烯酸甲酯（PMMA）和聚苯乙烯（PS）聚合物基质中合成荧光硫属化锌（ZnO、ZnS和ZnSe）纳米颗粒的简单方法。通过PMMA/PS-Zn(acac)₂H₂O在甲苯中的水热反应获得了高度分散的小尺寸球形ZnO纳米颗粒（3-5纳米）。通过将PMMA/PS-Zn(acac)₂H₂O在甲苯中与硫脲或硒氢化钠水溶液进行非均相搅拌来制备ZnS和ZnSe纳米颗粒。有趣的是，ZnO和ZnS-PMMA薄膜在暴露于氨时显示出强烈的荧光猝灭。
