【摘要】：本文采用熔融法和可控析晶法分別制備磷酸鹽玻璃和微晶玻璃,采用DSC,XRD,SEM和熒光光譜儀研究了玻璃組成對(duì)玻璃形成能力的影響;稀土摻雜磷酸鹽玻璃的光譜特性,以及熱處理制度和共摻稀土離子對(duì)微晶玻璃發(fā)光性能的影響,得到如下結(jié)論:1.探討了玻璃組成對(duì)SrO-ZnO-P2O5(SZP)體系玻璃形成能力的影響:添加適量的氧化物(K2O、Al2O3、B2O3、Sb2O3)能提高玻璃的穩(wěn)定性和玻璃形成能力。其中,添加K2O對(duì)提高玻璃形成能力最為有效。當(dāng)K2O=2%mol時(shí),穩(wěn)定性參數(shù)?T和H'分別為107和0.2198,比基礎(chǔ)玻璃的?T?93和H'?0.1876大為提高。2.系統(tǒng)研究了稀土離子摻雜SrO-ZnO-P2O5-K2O(SZPK)玻璃的發(fā)光性能:理清了單個(gè)稀土離子(Tm3+、Tb3+、Sm3+、Eu3+、Mn2+、Dy3+)摻雜SZPK玻璃的光譜特性和顯色情況:在近紫外激發(fā)下,摻Tm3+玻璃樣品呈藍(lán)光發(fā)射;摻Tb3+玻璃樣品呈綠光發(fā)射;摻Sm3+、Eu3+、Mn2+玻璃樣品均呈紅光發(fā)射;摻Dy3+玻璃樣品呈白光發(fā)射。在近紫外激發(fā)下,雙摻Tb3+/Eu3+和Tb3+/Sm3+玻璃樣品的色坐標(biāo)分別為(0.360,0.324)和(0.335,0.327),與標(biāo)準(zhǔn)白光的色坐標(biāo)(0.333,0.333)接近。3.研究了在近紫外激發(fā)下三摻離子玻璃樣品的光譜特性。對(duì)于三摻Tm3+/Tb3+/Eu3+的玻璃樣品,隨著Tb3+含量的增加,發(fā)光顏色從白光區(qū)逐漸過(guò)渡到綠光區(qū);對(duì)于三摻Tm3+/Tb3+/Mn2+的玻璃樣品,隨著Mn2+含量的增加,發(fā)光顏色從綠光區(qū)逐漸過(guò)渡到白光區(qū)。熒光壽命衰減曲線及壽命計(jì)算表明:Tm3+、Tb3+到Mn2+存在能量轉(zhuǎn)換。當(dāng)Mn2+摻雜量超過(guò)2%mol時(shí),出現(xiàn)濃度淬滅現(xiàn)象。4.研究了多離子摻雜微晶玻璃樣品的發(fā)光性能,探討了熱處理溫度對(duì)樣品發(fā)光強(qiáng)度的影響。結(jié)果發(fā)現(xiàn):隨著熱處理溫度的升高,晶粒析出增加,發(fā)光強(qiáng)度也隨之增強(qiáng)。析出的功能主晶相為SrZnP2O7。此外,研究了三摻Ce3+/Tb3+/Mn2+微晶玻璃樣品的光譜特性。隨著Mn2+含量的增加,Ce/Tb/Mn三摻微晶玻璃的發(fā)光顏色逐漸由冷白光區(qū)往暖白光區(qū)移動(dòng)。
[Abstract]:Phosphate glass and glass ceramics were prepared by melting and controllable crystallization methods. The effects of glass composition on the glass forming ability were studied by DSC, XRD, SEM and fluorescence spectrometer, the spectral properties of rare earth doped phosphate glasses, and the effects of heat treatment and Co doped dilute soil ions on the luminescence properties of glass ceramics were obtained. The following conclusions are as follows: 1. the effect of glass composition on the glass forming ability of SrO-ZnO-P2O5 (SZP) system is investigated. Adding a proper amount of oxide (K2O, Al2O3, B2O3, Sb2O3) can improve the glass stability and glass forming ability. Among them, the addition of K2O is the most effective for improving the glass forming ability. When K2O=2%mol, the stability parameters, T and H'are 107 and 0.219, respectively. 8, compared with the basic glass? T? 93 and H'? 0.1876, the luminescence properties of rare earth doped SrO-ZnO-P2O5-K2O (SZPK) glass were studied by.2. system: clear the spectral characteristics and color rendering of single rare earth ions (Tm3+, Tb3+, Sm3+, Eu3+, Mn2+, Dy3+) doped SZPK glass. The glass samples were emitted green light; the samples of Sm3+, Eu3+ and Mn2+ glass were all red light emission, and the samples doped with Dy3+ glass were emitted in white light. Under the near ultraviolet excitation, the color coordinates of the double Tb3+/Eu3+ and Tb3+/Sm3+ glass samples were respectively (0.360,0.324) and (0.335,0.327), and the standard white light color coordinates (0.333,0.333) were close to.3.. The spectral characteristics of the lower three doped glass samples. For three Tm3+/Tb3+/Eu3+ doped glass samples, with the increase of Tb3+ content, the luminescence color gradually transition from the white light region to the green light region. For three Tm3+/Tb3+/Mn2+ doped glass samples, with the increase of Mn2+ content, the luminescence color transition from green area to white light region. Fluorescence lifetime attenuation curve. The calculation of line and life shows that there is energy conversion between Tm3+, Tb3+ and Mn2+. When Mn2+ doping exceeds 2%mol, the concentration quenching phenomenon appears.4. to study the luminescence properties of multi ion doped glass ceramics, and the effect of heat treatment temperature on the luminescence intensity of the samples. The light intensity is also enhanced. The precipitated functional main crystal phase is SrZnP2O7., and the spectral properties of three Ce3+/Tb3+/Mn2+ doped glass ceramics are studied. With the increase of Mn2+ content, the luminescence color of Ce/Tb/Mn doped glass ceramics is gradually moved from the cold white light region to the warm white light region.
