“…When the Cr 3+ ions transfer from the amorphous glass phase to the crystal phase, the bandgap of the Cr 3+ ions changes with their coordination environment alternation, leading to an obvious blueshift in the absorption band of Cr 3+ after heat treatment. [ 32 ]…”

To improve the utilization efficiency of chlorophyll to sunlight, Tm3+/Cr3+ codoped dual‐phase glass‐ceramics are successfully fabricated as a dual‐light conversion material by the conventional melt‐quenching technique with subsequent heat treatment. Exploiting the radius difference in atomic size, Tm3+ and Cr3+ ions have been rationally designed entering into the NaYF4 and NaAlSiO4 crystal phase, respectively, to avoid detrimental energy quenching. The resulted dual‐phase glass‐ceramics exhibit a great emission enhancement compared to the precursor glass. No obvious lifetime degradation in the codoped glass‐ceramic further proves the successful incorporation of Tm3+ and Cr3+ in distinguished crystalline phases. Utilizing the dual‐phase glass‐ceramics, the useless sunlight can be converted into the desired red/blue region and reabsorbed by the chlorophyll. The Tm3+ ions convert ultraviolet light into the blue region, and the Cr3+ ions transfer green light to the red emission. With the utilization of Tm3+/Cr3+ codoped dual‐phase glass‐ceramics in the greenhouse, the photosynthesis process can be promoted, and furthermore, the production of crops can be improved, indicating the potential applications in the field of green agriculture.

A series of chromium borosilicate glasses double doped with Na2O and ZnO are prepared by melt quenching technique. Field Emission Scanning Electron Microscope (FESEM) showed a uniform distribution of ZnO within the glass matrix. Fourier-transform infrared (FT-IR) spectroscopy identified borate-oxygen defects while optical absorbance revealed that chromium Cr2O3 is composed of Cr6+ and Cr3+ oxidation states. X-ray photoelectron spectroscopy (XPS) validated the presence of borate and chromium-related defects via O1s, B1s, and Cr peaks. The substitution of Na2O with ZnO as polarizable component, proved presence of Zn2+ and Zn4+ cations which enables ZnO to act as both roles of glass modifier and a former. The evaluated optical linear refractive index and extinction coefficient in the spectral range 400–2500 nm showed an increase in the refractive index which is attributed to zinc’s high polarizability and limited tendency for tetrahedral coordination. The optical energy gap is positively correlated with increasing ZnO content in mol.%. The impact of ZnO concentration on wavelength at zero material dispersion (λWZMD) was also calculated and compared to silicate and germinate glasses proved suitability of the studied glass for photonic applications particularly data transmission in the wavelength range 1.6024–1.8855 μm. Thermal parameters were calculated using differential scanning calorimetry (DSC) to evaluate glass forming ability dependence on the introduced ZnO.
