We found out one kind of new orange-red long afterglow material La2O2S: Eu3+, Mg, Zr.2 In the phosphor Gd2O2S, Mg, Ti which was prepared by high-temperature solid-state method, the orange afterglow phenomenon can be seen after illuminated with UV light.3 Using the high-temperature solid-state method, Gadolinium oxysulfide phosphors doped with rare earth ions were synthesized. We can observe the red or orange phosphorescence in Gd2O2S doped with Eu3+, Sm3+, Tm3+, Yb3+, Dy3+, Er3+, Nd3+or Ho3+. This is a new result of the long afterglow phosphors research.4 Using the microwave radiation method, the new Sm3+ doped gadolinium oxysulfide phosphor, which has the orange-red long afterglow emission after illuminated with UV light or visible light, was synthesized for the first time.5 In fluorescent materials YOX doped with europium ions, the long afterglow phenomenon wasnt observed but the blue luminescence of Eu2+ and red luminescence of Eu3+ are simultaneously examined. This is a new result of the valence stability and change of Eu2+ in yttrium oxyhalide .We systematically studied the effects of the host, addition agents and reaction atmosphere on the valence change and fluorescence property of europium ions.

经过系统的研究总结得到以下的结论与成果： 1采用高温固相反应法合成了一系列稀土离子掺杂的硫氧化镧发光粉，发现了该体系中Eu~(3+)的长余辉发光，从而得到一种迄今未见文献报道的红色长余辉发光材料：La_2O_2S：Eu~(3+)，Mg，Zr； 2在Gd_2O_2S，Mg，Ti磷光粉中观察到橙色的长余辉发光现象； 3采用高温固相反应法合成了一系列稀土离子掺杂的硫氧化钆磷光粉，在掺杂Eu~(3+)、Sm~(3+)、Tm~(3+)、Yb~(3+)、Dy~(3+)、Er~(3+)、Nd~(3+)、Ho~(3+)的Gd_2O_2S中观察到红色和橙色长余辉发光； 4首次采用微波法合成了Gd_2O_2S：Sm~(3+)，Mg，Ti磷光粉，该磷光粉经紫外或可见光激发后呈现明显的橙红色长余辉发光； 5在YOX中同时观察到Eu~(2+)和Eu~(3+)的发射，系统研究了基质、添加剂及反应气氛对Eu价态和发光的影响。

Synthesizing new compounds are always the goal of chemist. Recent ly, the progress of the hydrothermal synthesis method is giving a new method to synthesize new compounds. The hydrothermal synthesis method is prefectly applied to synthesizing the tunnling materials, micro-and meso-porous mat erials as well as some new materials, so this method obtained the intrest of che mist.

The current antifungal agents used in clinics usually have severe side-effects, it is necessary to seek for new antifungal agents with known or new mechanisms. China has abundant resources in traditional Chinese medicine, therefore exploition of new antifungal agents therefrom is a feasible way.We have screened antifungal activities of 14 ethanolic extracts from traditional Chinese medicines and 21 natural products by using Saccharomyces cerevisiae GL7 and Prototheca wickerhamii as the model microoranganisms. Among the TCMs tested, Cortex Phellodendri, Flos Caryophylli, Fructus Mume, Rhizoma Coptidis and Radix Sophorae tonkinensis showed high antifungal activity. This study layed certain foundation for the development of new antifungal agents.
