Observation of paramagnetic point defects in BBO (β-BaB2O4) crystals

Growth and optical properties of Nd 3+ -doped Ba 2 Na 3 [B 3 O 6 ] 2 F crystals

“…% and higher, the authors of [16] observed the peaks of thermostimulated luminescence (TSL) at 123, 200 and 240ºɋ with emission maximum near Ȝ = 400 nm. At lower sodium content the TSL peaks at 80-90ºɋ had demonstrate emission near 360 nm [17,18]. This evidences that PLE bands for 300-450 nm emission, located in the 200-215, 220-250, and 250-295 nm ranges belong to different luminescence centers [18][19][20][21][22][23].…”
