| 1 | Spectral Property and Stability of Color Centers in Alkali Halide Crystals Induced by He^(+)Ion Implantation at Room Temperature显示文摘Thin colored layers with high density defect centers could be produced on alkali halide crystals implanted by 300-400keV He^(+)ions at room temperature.Besides well known absorption bands,several new absorption bands and colloid absorption band are observed in the crystals,such as 520 and 842nm absorption bands in the implanted LiF crystals,840nm absorption band in the implanted NaF:OH^(-)crystals,and 875 nm absorption band in the implanted NaC1:OH^(-)crystals. | GU Hongen CHEN Zhifang LI Zhijuan | 1993 | Chinese Physics Letters1993，10，3： | 2 |
| 2 | Low-Temperature Optical Spectra and Zero-Phonon Transitions of Color Centers in γ-Rayed Sodium Fluoride Crystals显示文摘A lot of narrow lines.on R_(2),R^(+),N_(1),N^(-) and some other un kowll centers have been observed in γ-raycd pure and doped sodium fuoride crystals in the temperature range of 9-77 K.The proper laser irradiation was used for strengthening the zero-phonon lines and the relative explanation was given.The spectral properties and thermosta-bilities of the lines were in vestigated systematically at difcrent temperatures. | GU Hongen | 1993 | Chinese Physics Letters1993，10，9： | 2 |

| 7 | PHOTOIONIZATION AND TUNABLE LASER OF COLOR CENTERS IN KMgF_(3)显示文摘The density of 570nm centers in KMgF_(3) crystals colored by electron beam bombardment at 200K could be increased by irradiating the crystals with 337nm,400nm,and 445nm lasers at room temperature or 200K,respectively.The near infrared laser operation using 570nm centers in KMgF_(3) crystals was realized at room temperature.The tunable range of the laser is from 720nm to 820nm. | GU Hongen QI Lan RUAN Yongfeng | 1990 | Chinese Physics Letters1990，7，6： | 0 |
| 8 | RFPRODUCTION OF HIGH DENSITY F_(2)^(+) CENTERS IN UNDOPED AND DOPED SODIUM FLUOWE CRYSTALS显示文摘F_(2) centers in colored undoped and doped NaF crystals can be converted nearly completely into F_(2)^(+) centers with the high density of more than 10^(17)cm^(-3) by irradiating the crystals with a 505nm laser at room temperature.A process of conversion from F_(2)^(+) to (F_(2)^(+))^(*) centers in the NaF crystals doped with divalent metal ions such as Mn^(++),Mg^(++) and Ni^(++) after the 505nm laser irradiation was observed in our experiments. | GU Hongen QI Lan | 1990 | Chinese Physics Letters1990，7，1： | 0 |
