Description
本發明係關於一種螢光材料,更特別關於此種材料於紫外光發光裝置之應用。
無機螢光材料(Phosphors),其激發與發光等項特性多是由「主體材料(Host materials)」、「活化劑/發光中心(Activators)」及其他「摻雜物」(Dopants)等組成因素所決定,亦即由不同的主體材料或摻雜物所組成的螢光材料,將可能具有相異的發光特性,而「組成」自然地也成為調控螢光材料光電特性的最重要因素。其中,無機螢光材料的主體材料多數由硫化物(Sulfides)、氧化物(Oxides)、硫氧化物(Oxysulfides)與其他複合氧化物(Complex oxides;Silicates、Aluminates、Phosphates etc.)所組成,近年來則有逐漸朝往氮化物(Nitrides)與氮氧化物(Oxynitrides)發展的趨勢;至於活化劑/發光中心則主要為過渡元素(Transition metal elements)或稀土族元素(Rare-earth elements)的離子為主。
未來光源需符合低汞/無汞的環保訴求,是故高效率的氙準分子燈(Xe2 *
excimer lamp)有可能成為未來重要應用的光源。在實際應用時為符合放射波長的特性需求,氙準分子燈常需搭配螢光材料進行光轉換。氙準分子燈主要的放射波長為172nm的真空紫外線(Vacuum ultra violet、VUV),經適當螢光材料光轉換後,可放射UV-B(280~320nm)
或UV-C(200~280nm)。UV-B可應用於光醫療(Phototherapy),比如治療乾癬(Psoriasis)、白斑病(Vitiligo)、異位性皮膚炎(Atopic dermatitis)等皮膚病。UV-C可應用於殺菌(Disinfection)或純化(Purification;TOC reduction)等各項領域。目前能搭配氙準分子燈的紫外線放射螢光粉相當少見,因此亟需開發新穎的螢光粉以符上述需求。
本發明一實施例提供一種螢光材料,具有化學式如下:M3-2x
M’x
(M”1-y-z

,其中M係Li、Na、K、或上述之組合;M’係Ca、Sr、Ba、Mg、Zn、或上述之組合;M”係Sc、Y、La、Lu、Al、Ga、In、或上述之組合;0x1;0<y0.15;以及0<z0.7。
本發明一實施例提供一種紫外線發光裝置,包括:激發光源;以及上述之螢光材料,其中激發光源之放射波長介於140nm至240nm。
一般而言,磷酸鹽類主體材料多數具有寬能隙特性,可以搭配不同活化劑而展現出各種相異的激發與放射特徵,可謂是多功能性的主體材料系統。本發明之實施例選擇較罕見的MM’M”(PO4

磷酸鹽類主體材料可以作為紫外光放射螢光材料,並可進一步結合Xe2 *
