Abstract in Portuguese
Neste trabalho apresentamos uma nova classe de vidros de fluoretos de metais pesados (HMF) baseados nos fluoretos de índio (InF3) de composição InSrBaZnGdNa e InSrBaZnGaNa. Realizamos um estudo das propiredades físicas (tais como: índice de refração, temperaturas características e estabilidades) e óticas (absorção, emissão e tempo de vida) de vidros puros e dopados com Nd ou Pr. As propriedades estão comparadas com aquelas dos vidros ZrBaLaAlNa (ZBLAN). A principal característica dos vidros de fluoretos de índios puros é a extensa transmissão no IV (até 8330 nm), maiores que a do ZBLAN (até 6650 nm). Tanto os vidros dopados com Nd como com Pr são materiais promissores para o desenvolvimento de laser com emissões a 1050 e 1320 nm nos vidros de Nd e a 1320 nm no vidro com Pr e amplificadores óticos para telecomunicações na janela ótica centrada a 1300 nm, uma vez que apresentam bandas de emissão a 1315 nm (InSBZnGdN), 1317 nm (InSBZnGdN:Nd) e a 1320 nm (InSBZnGdN:Pr).

Abstract in English
We present a new class of heavy metals fluoride glasses (HMF) of InSrBaZnGdNa and InSrBaZnGaNa compositions. We have realized a study of the physical properties such as refraction index, characteristic temperatures, stability and optical properties such as absorption, emission, lifetime of pure, Nd or Pr doped glasses. These properties are similar to those obtained for glasses of ZrBaLaAlNa (ZBLAN) composition. The main characteristic of pure indium fluoride glasses is their larger transmission window in the infrared region (8330 nm) compared to ZBLAN composition (6650 nm). Rare earth doped glasses are promising materials for the development of glasses laser with emission in the 1050-1320 nm range (Nd) and 1320 nm (Pr), as well as optical amplifiers for telecommunication in the optical window centered at 1300 nm, as prominent emission bands are located at 1315 nm (InSBZnGdN), 1317 nm (InSBZnGdN:Nd) and 1320 nm (InSBZnGdN:Pr).
