“…The observed bands were labeled with the letters A, B, C, and D. According to the literature [10,43,44], A band is ascribed to the valence to conduction band transition of the host [O (2p)-Ti (3d)], B band resulted from the Pr 3+ to metal charge transfer state (also known as intervalence charge transfer IVCT state), and C band is assigned to the 3 H4 to 3 Pi (I = 0, 1, 2) transitions (f-f transition), respectively. Moreover, the D band demonstrated the lowest field component of the 4f5d state of Pr 3+ [44,45]. Broadbands were observed, which became sharper with Zr 4+ content, increasing in the UV range from 230 nm to 475 nm.…”

The Pr3+-doped solid solutions from (Ba,Ca)(Ti,Zr)O3 (BCTZO) system were successfully synthesized using an efficient and low-energy consuming route—the Pechini method combined with the sintering at relatively low temperature (1450 °C). The obtained materials were characterized by means of X-ray diffraction (XRD) and scanning electron microscopy (SEM). The dielectric properties were systematically studied. The Pr3+-doped BCTZO diphasic material generates intense and broad red photoluminescence (PL) emission at room temperature. The optical properties were significantly improved with the Ti4+ substitution by Zr4+ ions. As a result, the Pr3+-doped (Ba,Ca)(Ti,Zr)O3 ceramics is a promising candidate for environmentally friendly, multifunctional material by combining good dielectric and photoluminescent properties with prognosis for the manifestation of strong photoluminescent and mechanoluminescent effects.

“…Furthermore, the additional excitation band centered at 264 nm (D band) in Fig. 2(b) is ascribed to the lowest field component of the 4f5d state of Pr 3+ [16,20,21].…”
