AB  - Metal-organic frameworks with perovskite structures have recently attracted 
      increasing attention due to their structural, optical, and phonon properties. 
      Herein, we report the structural and luminescence studies of a series of six 
      heterometallic perovskite-type metal-organic frameworks with the general formula 
      [EA](2)NaCr(x)Al(1-x)(HCOO)(6), where x = 1, 0.78, 0.57, 0.30, 0.21, and 0. The 
      diffuse reflectance spectral analysis provided valuable information, particularly 
      on crystal field strength (Dq/B) and energy band gap (E(g)). We showed that the 
      Dq/B varies in the 2.33-2.76 range depending on the composition of the sample. 
      Performed Raman, XRD, and lifetime decay analyses provided information on the 
      relationship between those parameters and the chemical composition. We also 
      performed the temperature-dependent luminescence studies within the 80-400 K 
      range, which was the first attempt to use an organic-inorganic framework 
      luminescence thermometer based solely on the luminescence of Cr(3+) ions. The 
      results showed a strong correlation between the surrounding temperature, 
      composition, and spectroscopic properties, allowing one to design a temperature 
      sensing model. The temperature-dependent luminescence of the Cr(3+) ions makes 
      the investigated materials promising candidates for noncontact thermometers.
