Optical properties of Er3+-singly doped and Er3+/Yb3+-codoped novel oxyfluoride glasses

Spectroscopic properties of Er3+ in a oxyfluoride glass and upconversion and temperature sensor behaviour of Er3+/Yb3+-codoped oxyfluoride glass

“…Upconversion of infrared-to-visible in rare-earth doped oxyfluoride glasses has been extensively investigated [1][2][3][4][5][6], due to the potential applications of these materials in areas like visible lasers, optical data storage, color display, under-sea optical communications and sensors [7][8][9][10][11][12][13][14]. Among the rare-earth ions, Er 3 + ion is one of the important active ions due to its convenient energy level structure exploitable in upconversion processes.…”

Spectroscopic properties of Er3+-doped and Er3+/Yb3+-codoped PbF2–MOx (M=Te, Ge, B) oxyfluoride glasses

“…In recent years, the upconversion process of rare-earth ions under infrared laser diode (LD) excitation in transparent hosts has been studied extensively due to potential applications in the fields such as 3D display, optical data storage, under-sea optical communications, biomedical diagnostics, sensors as well as room temperature infrared pumped visible lasers [1][2][3][4][5][6]. It is well known that Er 3+ is the most commonly used as an activator among the rare-earth ions [1][2][3][4][7][8][9][10][11][12][13].…”

“…It is well known that Er 3+ is the most commonly used as an activator among the rare-earth ions [1][2][3][4][7][8][9][10][11][12][13]. When a rare-earth ion is chosen as the activator of an upconversion material, the host composition becomes a critical factor to be designed since its spectroscopic properties depend strongly on the local environment of hosts [5,14,15].…”

“…The research for excellent hosts still attracts much attention of scientists. At present, heavy metal oxyfluoride glass [4,11,16] is considered to be one of the most promising materials because it can combine well good optical, mechanical and thermal-stable properties of the oxides with lower phonon energy of fluorides which can effectively reduce multiphonon decay of excited states in rare-earth ions and thus enhance the optical quantum efficiency [10,17,18].…”

Enhancement of upconversion luminescence in Tm3+/Er3+/Yb3+-codoped glass ceramic containing LiYF4 nanocrystals

“…In recent years, rare-earth (RE) ions doped glasses have attracted much attention due to their applications on threedimensional displays, fiber amplifiers, solid state lasers, and fiber lasers [1][2][3][4]. Among them, the oxyfluoride glass ceramics have been paid much attention due to their combined advantages of oxide glass matrix and fluoride crystal-high chemical and mechanical stabilities and low phonon energy [5].…”
