Copper Doped Phosphate Glass as an Optical Bandpass Filter

Optical applications of transition metal ion doped phosphate glasses

“…The bandwidths for a wavelength of 417 nm are 5.26 nm for the lowest dopant and 2.20 nm, for the highest dopant, similarly, the bandwidth for 415.53 nm is 0.47 nm. The full-wave half maximum (FWHM) for the first peak for low and highest dopants are 2.89 and 1.22 nm, similarly, the FWHM value for the second peak for highest dopant is o.35 nm, and it supports the works of [17,18]. Prepared vanadium ion-doped glasses are having excellent optical properties and are useful for optical applications like optical band pass filters in the visible region and also for wear glasses used for seasonal temperatures.…”

“…The oxidation states of vanadium are +4 and +5, and exchange of electrons occur by the mechanism of transport in between the two oxidation states [15]. These glasses have high electrical conductivity, low dispersion, low melting temperature, UV transmission, low softening temperature and high thermal expansion coefficient [16,17]. These glasses possess unique optical, thermal, mechanical and physical properties when they contain transition metal ion, and have applications in an optical band-pass filters, fluorescence microscopy, sun-glasses for the protection from ultraviolet light, laser, optical devices, clinical chemistry, photography and fiber optics [18].…”

Infrared Nanosecond Laser Texturing of Cu-Doped Bioresorbable Calcium Phosphate Glasses

“…As mentioned before, Cu-doped phosphate glasses provide bio-resorbability and antibacterial properties due to the inclusion of Cu 2+ ions in the glass matrix [28]. Doping of metal species into the glass also causes a reduction in the absorption bandgap at both ultraviolet (UV) and IR wavelengths [29]. Characterizing the UV-to-IR absorption of the glass gives an understanding of the feasibility of laser processing of this phosphate glass at the laser wavelength of 1064 nm.…”
