Abstract

The invention provides a preparation method for sensitization-enhanced green light-emitting high-silica glass. The preparation method comprises the following steps: melting borosilicate glass, controlling heat treatment conditions, restricting the degree of phase-splitting and carrying out acid leaching so as to obtain porous glass which contains a part of residual Na <+> ions; dipping the porous glass in a solution containing Tb and Eu ions for immersion and doping; and sintering the porous glass at a high temperature in a reducing atmosphere so as to obtain the compact sensitization-enhanced green light-emitting high-silica glass. According to the invention, since a glass structure has Na <+>, energy transfer between ion is achieved and the excitation band of Tb<3+> ions is transferred and becomes about 320 nm instead of about 245 nm, thereby not only effectively increasing the excitation bandwidth of Tb<3+> but also greatly improving luminous intensity. The sensitization-enhanced green light-emitting high-silica glass prepared in the invention is expected to be used as a novel luminescence and laser material in a variety of fields like scientific research, national defense and health care.

Description

technical field

[0001] The invention relates to a green-light-emitting high-silica glass, in particular to a method for preparing a sensitized and enhanced green-light-emitting high-silica glass. Background technique

[0002] Electromagnetic waves of various bands have different transmission characteristics in different media. Similar to the light-transmitting window in the atmosphere, the attenuation of seawater to blue-green light in the 450-550nm band is much smaller than that of other bands. Therefore, blue-green lasers in this band can be used for new equipment such as underwater target detection, control, and communication.

[0003] At the same time, in medicine, the absorption peak wavelength of red blood cells and other biological tissues is also around 542nm, and the more mature commercial 532nm lasers are not in this optimal position. The development of lasers with more matching wavelengths can greatly improve the detection sensitivity of corresponding medical eq...
