Structure and temperature effects on Nd3+ spectra in polycrystalline mixed scandium aluminum garnets Y3Sc Al5−O12

Epitaxial Growth of Single Crystal YAG for Optical Devices

“…In the Sc-doped YAG films, we observe that the longer Sc-O bonds results in distinct peaks in the Raman spectra based on a regular substituting of Al 3+ by heavier Sc 3+ ions. In Figure 14, the peaks seen between 680 and 1350 cm −1 can be assigned to the internal stretching vibrations between scandium ions and oxygen in the tetrahedral (Sc,Al−O 4 ) unit [40,41]. A detailed analysis of the Raman spectra of compositions will described in a subsequent communication.…”

Design and synthesis of a novel blue-emitting CaNaSb2O6F:Bi3+ phosphor for optical temperature sensing

“…12 Furthermore, the frequently observed shifts of emission peaks and/or excitation wavelengths with the temperature change may also undermine the stability of the measurement. 17,18 On the other hand, divalent rare earth ions with wide band excitation/emission spectra have low chemical stability and it is difficult for them to meet the practical application requirements in the field of temperature sensing. Moreover, rare earth ions also have the disadvantages of high production cost, poor recyclability and limited mineral abundance, which further limit their practical application.…”
