Photoelectric properties of glass-ceramics containing KTb₂F₇ nanocrystals for UV detection.

For excitation wavelengths from 200 to 255 nm, the relative luminescence intensity always shows an increasing trend, and then it decreases significantly in the range of 230–245 nm, but it shows an increasing trend after 245 nm and then decreases significantly until the excitation wavelength reaches 260–270 nm.
