Investigation of Luminescence Properties of Tb3+ Ions In Gadolinium Borogermanate Glasses For Green Laser Application

Abstract

Tb3+ doped borogermanate glasses with 30B2O3-40GeO2-(30-x)Gd2O3-xTb2O3 (x=1,2,3,5 and 7

mol%) composition have been prepared by conventional melt quenching technique. The optical and luminescence

properties of prepared glasses were characterized by absorption, photoluminescence and decay time measurements.

The photoluminescence spectra of Tb3+ doped borogermanate glasses exhibit intense emission in green region

(5D4→7FJ , J = 3,4,5 and 6) and weak emission in blue region (5D3→7FJ , J = 3,4 and 5) under 378 nm excitation.

Among them 5D4→7F5 transition (541 nm) gives the most intense green emission. Concentration quenching is

observed beyond the doping level of x=5. The ratios of integrated emission intensities of 5D4→7F5 to 4D3→7F4

transitions called as green to blue ratio (G/B) have been evaluated as a function of Tb3+ ion concentration. Decay

time of 5D4→7F5 transition of Tb3+ ions was found to be 1.801 ms. The color coordinates of the prepared glasses are

located at the green region of the CIE diagram.

Yeşil Lazer Uygulaması İçin Gadolinyum Borogermanat Camlarındaki Tb+3 İyonlarının Lüminesans Özelliklerinin İncelenmesi

Abstract

30B2O3-40GeO2-(30-x)Gd2O3-xTb2O3 (x=1,2,3,5 ve 7 % mol) kompozisyonuna sahip cam sistemleri eritme

tavlama yöntemi ile sentezlenmiştir. Hazırlanan camların optik ve lüminesans özellikleri soğurma, fotolüminesans

ve bozunma zamanı ölçümleri ile incelenmiştir. Tb+3 katkılı borogermanat camlarının 378 nm uyarma altında elde

edilen fotolüminesans spektrumları yeşil bölgede şiddetli yayınlanma (5D4→7FJ , J = 3,4,5 ve 6) ve mavi bölgede

zayıf yayınlanma (5D3→7FJ , J = 3,4 ve 5) piklerinden oluşmaktadır. Bunların arasında en şiddetli 5D4→7F5 (541 nm)

geçişi yeşil yayınlanma göstermektedir. x=5 katkı miktarından sonra konsantrasyon baskılanması gözlenmiştir.

5D4→7F5 ve 5D3→7F4 yayınlanma piklerinin alanlarının oranı olan yeşil-mavi değerleri (G/B) Tb+3 iyon konsantrasyonunun

fonksiyonu olarak elde edilmiştir. Tb+3 iyonunun 5D4→7F5 geçişinin bozunma zamanı 1.801 ms olarak

bulunmuştur. Hazırlanan camların elde edilen renk koordinatları CIE diyagramının yeşil bölgesinde yer almaktadır.
