摘  要:研究了纳米相氟氧化物玻璃陶瓷中Er^(3+)Yb^(3+)离子对的量子剪裁发光造成的强的光谱调制现象。测量了Er^(3+)Yb^(3+)双掺纳米相氟氧化物玻璃陶瓷的X射线衍射谱、表面形貌、激发光谱、吸收光谱、和发光光谱;而且也与Tb^(3+)Yb^(3+)双掺纳米相氟氧化物玻璃陶瓷的相对应的光谱参数进行了比较。发现378nm光激发样品(A)Er(1%)Yb(8.0%)∶FOV和样品(B)Er(0.5%)Yb(3.0%)∶FOV所导致的652.0nm红色发光强度为522nm光激发时的680.85倍和303.80倍;我们还发现378nm光激发所导致的样品(A)Er(1%)Yb(8.0%)∶FOV和样品(B)Er(0.5%)Yb(3.0%)∶FOV的652.0nm红色发光强度为样品(C)Er(0.5%)∶FOV的491.05和184.12倍。我们还发现在378nm光激发时的样品(A)Er(1%)Yb(8.0%)∶FOV和样品(B)Er(0.5%)Yb(3.0%)∶FOV的{978.0和1 012.0nm}红外发光强度依次分别为样品(C)Er(0.5%)∶FOV的{58.00和293.62}倍和{25.11和67.50}倍。更进一步,对于652.0nm波长发光的激发谱,发现(A)Er(1%)Yb(8.0%)∶FOV和(B)Er(0.5%)Yb(3.0%)∶FOV的378.5nm激发谱峰强度是(C)Er(0.5%)∶FOV的大约606.02和199.83倍。同时,也发现样品(A)Er(1%)Yb(8.0%)∶FOV和样品(B)Er(0.5%)Yb(3.0%)∶FOV的一级量子剪裁红外1 012或978nm发光强度为样品(D)Tb(0.7%)Yb(5.0%)∶FOV的二级量子剪裁红外976nm发光强度的101.38和29.19倍。发现的该量子剪裁是目前所报道的最强的量子剪裁。因此,相信所发现的氟氧化物纳米玻璃陶瓷中Er^(3+)Yb^(3+)离子对的一级量子剪裁发光是强的可以作为量子剪裁层应用到提高晶硅太阳能电池的发电效率。研究结果也能加速对目前国际热点的下一代环保的光谱调制太阳能电池的探索。In this paper, the spectral modulation by the quantum-cutting luminescence of Er3+Yb3+ ion-pairs in nanophase oxyfluoride vitroceramics is studied. We obtained X-ray diffraction spectra, surface topographies, excitation, absorption, and luminescence spectra of Er3+Yb3+ nanophase oxyfluoride vitroceramics, and compared them with the corresponding parameters of a Tb3+Yb3+-codoped sample. We find that the 652.0 nm wavelength red luminescence intensity is enhanced by the factors of 680.85 and 303.80 for (A) Er(1%)Yb(8.0%)∶FOV and (B) Er(0.5%)Yb(3.0%)∶FOV, respectively, when they are excited by 378 nm light than when they are excited by 522 nm light. It is also found that the 652.0 nm red luminescence intensity is enhanced 491.05 and 184.12 times for (A) Er(1%)Yb(8.0%)∶FOV and (B) Er(0.5%)Yb(3.0%)∶FOV than (C) Er(0.5%)∶FOV when they are both being excited by 378 nm light. the results show that the {978.0 and 1 012.0 nm} infrared luminescence intensities of (A) Er(1%)Yb(8.0%)∶FOV and (B) Er(0.5%)Yb(3.0%)∶FOV are {58.00 and 293.62} and {25.11 and 67.50} times, respectively, larger than the corresponding ones of (C) Er(0.5%)∶FOV when both excited with 378 nm light. And further, the intensities of the 378.5 nm excitation peak of (A) Er(1%)Yb(8.0%)∶FOV and (B) Er(0.5%)Yb(3.0%)∶FOV are about 606.02 time and 199.83 times, respectively, larger than (C) Er(0.5%)∶FOV when 652.0 nm luminescence wavelength is selected as the fluorescence receiving wavelength to measure the visible excitation spectra in the range of 250~628 nm. Meanwhile, we also find that the first-order quantum-cutting infrared 1 012 or 978 nm luminescence intensities of (A) Er(1%)Yb(8.0%)∶FOV and (B) Er(0.5%)Yb(3.0%)∶FOV are about 101.38 and 29.19 times larger than the second-order quantum-cutting infrared 976 nm luminescence intensity of (D) Tb(0.7%)Yb(5.0%)∶FOV.
