采用传统的熔融猝灭技术制备了含少量NiO的氟氧化物玻璃，并用波长为1064或1080 nm的连续波激光在玻璃表面诱导了LaF{sub3}和CaF{sub2}晶体的空间择优晶化。包括LaF{sub3}晶体的点和线通过热辅助(300℃)图案化。C)激光({lambda}=1064 nm)，功率P=1W，照射时间10 S，扫描速度S=5{m}m/S。用功率P=1.7W、扫描速度S=2{u}m/S的激光({lambda}=1080 nm)在掺ErF{sub3}的氟氧化物玻璃中形成了由CaF{sub2}晶体组成的谱线，显微光致发光光谱测量证实了Er3+离子的掺入。提出了激光辐照线条是由LaF(Sub3)或CaF(Sub2)纳米晶与SiO(Sub2)基氧化物玻璃相组成的复合体。结果表明，Ni{sup2+}掺杂和激光照射相结合对氟化物在氟氧化物玻璃中的空间选择局域晶化是有效的。-图形摘要：本图显示了激光功率P=1.7W，扫描速度S=2{u}m/S在氟氧化物玻璃中产生的线条的偏振光学和共焦扫描激光显微照片。结果表明，该谱线由CaF纳米晶和氧化物玻璃相组成。这是第一次演示激光在玻璃中形成氟化物晶体的图案化。
Oxyfluoride glasses with a small amount of NiO are prepared using a conventional melt quenching technique, and the spatially selected crystallization of LaF{sub 3} and CaF{sub 2} crystals is induced on the glass surface by irradiations of continuous wave lasers with a wavelength of {lambda}=1064 or 1080 nm. Dots and lines including LaF{sub 3} crystals are patterned by heat-assisted (300 deg. C) laser irradiations ({lambda}=1064 nm) with a power of P=1 W and an irradiation time of 10 s for dots and a scanning speed of S=5 {mu}m/s for lines. Lines consisting of CaF{sub 2} crystals are also patterned in an ErF{sub 3}-doped oxyfluoride glass by laser irradiations ({lambda}=1080 nm) with a power of P=1.7 W and a scanning speed of S=2 {mu}m/s, and the incorporation of Er{sup 3+} ions into CaF{sub 2} crystals is confirmed from micro-photoluminescence spectrum measurements. It is proposed that the lines patterned by laser irradiations in this study are consisted of the composite of LaF{sub 3} or CaF{sub 2} nanocrystals and SiO{sub 2}-based oxide glassy phase. It is demonstrated that a combination of Ni{sup 2+}-dopings and laser irradiations is effective in spatially selected local crystallizations of fluorides in oxyfluoride glasses. - Graphical abstract: This figure shows the polarization optical and confocal scanning laser micrographs for lines obtained by laser irradiations with a laser power of P=1.7 W and a scanning speed of S=2 {mu}m/s in an oxyfluoride glass. It is proposed that the line consists of the composite of CaF{sub 2} nanocrystals and oxide glassy phase. This is the first demonstration on the patterning of fluoride crystals in glass by laser irradiations.
