The role of CeO2 insertion and gamma radiation in optoelectronic and ultrasonic transducer applications of PbO-B2O3 glasses
Source abstract
Abstract
Novel B 2O 3-PbO glass systems doped CeO 2 was developed and characterized. XRD and FTIR analyses were utilized to describe the glass structures. Chemical durability in 100 °C dis. H 2O for 16 h and other glass`s physical parameters e.g. density, molar volume, specific volume and oxygen packing density (OPD) were evaluated. Gamma irradiation (80 kGy) causes an enhancement in the glass properties like the aggregation of chemical durability by ∼ 50%, the density enhancement and the compactness. Ce 3+/Ce 4+ luminescent ions possess UV and blue emissions according to CIE chromaticity coordinates. Ultrasonic measurements demonstrated a novel application. The prepared glasses is used as lenses in medical ultrasonic transducers. They gained a high-quality factor, a narrow bandwidth, and collimated waves for more accurate medical diagnosis and early disease detection. The transducer with lens 2 CeO 2 mol% had the highest quality factor (6.9 %), the narrowest bandwidth (0.7 MHz), and revealed the highest optoelectronic efficiency.
