Figure 2. (A) Room-temperature PLE (blue) and PL (red) spectra of Lu3Sc1.98Ga3O12:0.02Cr3+ phosphor. (B) Normalized PL spectra of Lu3Sc1.98-xMgxGa3-xSixO12:0.02Cr3+ (x = 0.0-0.6) excited by 440 nm light. (C) Peak wavelength and FWHM of Lu3Sc1.98-xMgxGa3-xSixO12:0.02Cr3+ (x = 0.0-0.9). (D) Tanabe-Sugano diagram of Cr3+ in the perfect octahedral environment. (E) Integrated intensity of PL spectra of Lu3Sc1.98-xMgxGa3-xSixO12:0.02Cr3+ (x = 0.0-0.9) excited by 440 nm light. (F) DR spectra of Lu3Sc1.98-xMgxGa3-xSixO12:0.02Cr3+ (x = 0.0-0.9).
