Infrared-to-blue Upconversion in Tm-doped Oxyfluoroborate Glasses

Oxyfluoroborate 유리재료에서의 적외선-청색 상방 형광발생

In recent years, there has been an increasing interest in $Tm^{3+}$ doped crystals and glasses due to their potential applications as near infrared lasers and infrared to visible upconversion lasers for use in different fields such as medical surgery, eye safe laser radar, data storage, barcode reading and so on. Thulium ions have stable excited levels suitable for emitting blue upconversion fluorescence. (omitted)
