Конкретные составы стекол представлены в табл. 1.Specific compositions of glasses are presented in table. one.
На фиг. 1 и 2 показаны спектры люминесценции и пропускани цветных оптических стекол ОС-14, содержащих и не содержащих оксид иттерби .FIG. Figures 1 and 2 show the luminescence and transmission spectra of OS-14 colored optical glasses, containing and not containing ytterbi oxide.
При введении оксида иттерби интенсивность люминесценции резко уменьшаетс (фиг. 1), при этом на длине волны 1,0 мкм возникает слаба люминесценци иттерби , интенсивность которой зависит от количества введенного оксида иттерби . Возбуждение люминесценции осуществл ют галогенной лампой накаливани в области 0,3-0,6 мкм и гелий-неоновым лазером.With the introduction of ytterbium oxide, the luminescence intensity decreases sharply (Fig. 1), while at the wavelength of 1.0 µm, ytterbium luminescence appears weak, the intensity of which depends on the amount of ytterbium oxide introduced. The luminescence is excited by a halogen incandescent lamp in the range of 0.3-0.6 µm and a helium-neon laser.
В табл. 2 приведены значени интенсивноетей паразитной люминесценции и люминесценции иттерби при изменении его содержани в стекле и коэффициента пропускани полученных стекол.In tab. Figure 2 shows the intensity of the parasitic luminescence and ytterbium luminescence when the glass content and the transmittance of the obtained glasses change.
Использование предлагаемого изобретени обеспечивает получение цветных оптических стекол, не люминесцирующих в области длин волн короче 1 мкм, при практически неизменной спектральной зависимости коэффициентов пропускани The use of the present invention provides for obtaining colored optical glasses that do not luminesce in the wavelength range shorter than 1 µm, with a practically unchanged spectral dependence of transmittance
